Here's a portable AI image prompt for a soft watercolor rural landscape of (two car train at level crossing, sunset) with rice paddies and layered mountains plus foreground wild grasses/small flowers to keep washes loose and warm light while still maintaining small botanical detail.

soft watercolor illustration of a rural Japanese railway at golden hour sunset, a red and cream two-car train approaching a level crossing with lowered black and yellow barriers and glowing red warning lights, foreground of wild grasses and small white, yellow and orange wildflowers with visible brush texture, a person on a bicycle with a basket waiting beside the tracks, flooded rice paddies reflecting the sky, wooden utility poles and wires receding along the curved track, layered mountains and large luminous cumulus clouds in peach, gold, lavender and pale blue, loose transparent washes, visible cold-pressed paper texture, gentle granulation, warm diffused light with subtle lens flare, wide landscape composition
Crossing gate, red signal and two car train through flooded rice fields at sunset. This one comes apart in AI watercolor quickly. Either muddy washes or toy train or green blobs of foreground flowers. In this image the sky-washes are transparent. The low warm sun is behind ridge. Foreground is grasses with dry brush details on small white & yellow flowers.
What the prompt is describing
No, not a bunch of flowers on white paper. This is landscape watercolor with florals as foreground texture. Paper looks like cold-pressed to me, clouds and mountains have gentle granulation while the grasses along the bottom edge are sharper/drier brushwork. Light feels diffused and warm (peach/gold sky, lavender shadows, sage/ochre fields) and there's reflection on paddy water instead of hard edges.
It does matter in terms of wording. They respond to more concrete things like "transparent washes", "texture showing through the paper" and "loose edges". Instead of abstract words like "beautiful watercolor". It's also helpful when you name your colors (peach, gold, lavender, sage) so that it doesn't end up looking saturated orange for a sunset.
Building the prompt in parts
Keep the structure in three depths so the model does not flatten the scene:
- Foreground: "wild grasses and small white, yellow and orange wildflowers, dry-brush detail, shallow depth of field" — this anchors the floral keyword without asking for a centered bouquet. If you write only "flowers," you will get a vase.
- Midground: "level crossing with black and yellow barriers, red warning lights, a person on a bicycle waiting, red and cream two-car train on curved tracks, flooded rice paddies with reflections"
- Background: "layered mountains in soft washes, large cumulus clouds lit from below, low sun behind ridge with subtle flare, utility poles and wires receding"
Add this technique (only once, at the end): "soft watercolor illustration; loose transparent washes; visible cold-pressed paper texture; gentle granulation". By putting it at the end you minimize the risk of over stylizing the train into some sort of graphic icon.
For a related approach to isolated florals versus florals in context, see this whimsical floral illustration prompt which handles dense flower clusters on a lighter ground. The rural scene here is the opposite problem: sparse, small flowers scattered in grass.
Why the floral foreground is tricky
The first thing to fail in wide landscape framing are tiny wildflowers. If you're at 2k or more, the white/yellow dots will just be noise and the model may paint them over with generic green texture. Often if you give scale ("tiny wildflowers scattered (not a dense bouquet)") and brush treatment ("dry brush foreground soft washes sky") it helps (but these are untested suggestions). If that doesn't make the flowers show, try cropping tighter or adding "foreground detail in focus background washes soft"
The other problem is color bleed. If you over-weight "sunset" then everything will get pink from the warm sunset light. You need to keep in there "warm diffused light", and call out greens specifically, like "sage, olive and yellow green fields" so that your paddies don't disappear.
What to change when the result is wrong
If the train looks more like a photo than a painting, lower detail words (hyper-detailed) and raise "loose edges bleeding washes". If sky looks flat, then add "varied cloud washes / granulation paper white highlights" instead of dramatic sky.
If the crossing signals and japanese text on sign turn into a bunch of gibberish glyphs just say "crossing signal with red lights, small sign with illegible characters" or something because its really hard to render small text well in watercolor sim. Remember this is simulation not real photo it tries to simulate how pigment looks on paper but doesn't actually do proper optics/pigment physics so expect lens flare and reflections to be hand painted approximations also fine line work for wires, rails etc will jitter.
Exact model and settings for the reference image are not known, so treat the prompt above as a portable starting point, not a guaranteed reconstruction. An image-inspired prompt cannot guarantee an identical image, and the same wording will behave differently across generators. If you need a softer, more character-focused watercolor for comparison, this charming watercolor portrait prompt shows how the same wash vocabulary works at portrait scale.
Quick edit checklist
- Too much orange: replace "sunset" with "golden hour, peach and lavender sky"
- Flowers too large: change to "tiny scattered wildflowers among grasses"
- Paper texture missing: add "cold-pressed paper, visible texture, white of paper for highlights"
- Wires tangled: reduce to "single line of utility poles with simple wires" or remove wires entirely
