Chose to use the first picture, because it's easy. Like Tess. Hur hur (is dumb, deserves trash cans)
Dresses don't typically weave in and out of plants. That's clearly a plant being overlaid on top of said dress. There's a plant brush in GIMP that's close to this. There's one in Photoshop that's almost exactly this. Application of said brush with a smidge of smudge makes a convincing overlay. Even better (and the method I suspect was used) is a color-select copy and paste to snag leaves and then paste them elsewhere.
Dresses don't typically make perfectly straight lines, Tess.
I just really liked the obvious bubble of smudged shit here. Because it's obvious.
This color is replicated exactly nowhere else in this pattern. It appears to have been copied from the cactus next to it and then blotted in with a 20hd soft brush tool at 100% opacity. Hence why it goes over the dress and her flesh as well.
Not a shoop, but even Lovecraftian horrors would use the power of christ to save them from the dangly crotch string and lack of knees.
