Hi guys, 
I am studying characters and would like the opinion of you, I’m not working in the area but I really want to start.
Full Zbrush, BPR Render
Maya, Vray, Photoshop & Zbrush
Anatomy Study, i’m still doing this study. Right now I’m researching for more references on anatomy books for artists and the Internet. 
Would say the Princess feel short. You scale the shoulder and the head, but scaling the shoulders wider give the expectation to have a more taller character. Feel like she miss length in the legs. Or maybe it’s what your concept try to do.
Character design and lighting look fantastic! Personally I prefer the princess to be shorter.
