Tried to do this one a bit differently. Spent a lot of time coloring this so hopefully it turned out ok. Also its my first one to have a background. Could not decide to make the shirt see-through or not so I made two versions, this nicer one for everyone and there is a Ecchi version of this too
Cute background and character! There is good shading on this. The only thing is that your proportions are a bit off. So maybe work on that? C: Other than that I think you hit everything pretty spot on.
