I can imagine a variable proportion such as the flesh on the crotch being held out a bit by the clothes but it's hard to get a feel for if it looks right without reference.
Also, by holding my own arm out in her pose I see that her arm is either short or pointing behind her by a lot and foreshortened. It can be tricky to make that look right.
The coloring and skin tone is great all over. Her left leg's outer lines look uneven though. It's not too bad but I think the unevenness of that outer line clashes with the hard lines of the shorts and most other places.
Overall, I wish I could draw this good.
