I've been curious about whether I can create this 3d+2d fusion style, but it has been put on hold. Recently, I tried to create with a small amount of materials, so I tried it out. The first batch seems okay, with a loss of 0.126. Watercolor brushes, wooden desktops, and drawing paper are the three relatively stable elements. Decorative flowers need to be triggered by flower, and can also be triggered by wool ball decorations. Haven't tried much else yet.

【Style Features】Combining real scenes with 2d watercolor-style drawings.

【Recommended Basic Size】512x512 would be better, 512x768 is also acceptable.

【Recommended Base Model】The Final Fantasy of Fireflies and similar realistic style base models.

【Reference Tag Combination】<lora:layout01_v1:1.0> shouzhang, top down shot, layout, multimedium, no humans, still life, flowers, a painting of a vase of flowers in the style of watercolor sketch,

The underlined part can be replaced to change the content of the drawing paper artwork.

【Addendum】You can also test other painting style lora combinations, I only tried adding Simplified Watercolor Style Lora .

【Comparison of Lora Weights】Comparatively, lora still plays a role in composition and layout.

The rest is left for everyone to explore and experiment on their own. :D
