>>285172There...isn't exactly a whole lot of anatomy in the picture to remark on in the first place...
It's not bad, as far as animu goes, but from what I can see you may indeed have problems. The hands very in size a lot, which is okay for animu, but if you're going for realistic proportions they should approximately cover the face(not the entire head under the hairline, just from about chin to eyebrows). They can get smaller or larger, sure, but that's a pretty good baseline.
Other than that, there's not much to say, it's typical animu but pretty solid for typical animu. The figure in the center bothers me; the waist is a little wide compared to her shoulders and legs, so definitely watch that, and she's waaay too tense; your shoulders are too high up. Unless that's what you were intending. Also looks anorexic.
