your art is adorable, i really like your style!
but, i think you need to do some improving first before i personally would pay. specifically, we're looking at the torso and hip/thigh areas. youre definitely going to want to work on your anatomy there, as shoulders are too broad and then everything else becomes oddly skinny. rear ends seem a bit awkward, just in the way that they have an odd curve. i would definitely look at some tutorials on DA, practice some torsos and hip areas, and then i think you'd be ready

your style is lovely!!!
edit: oh, you can always also do freebies for practice~
