Practice OC

I figured, with the new year coming in, that it might be a good idea to practice some more little bits and piece, and so this character was born!

I don't have a name for her or anything, but I think I'll be working with her for a little while to practice and study darker skin tones, piercings, clothing design, lighting and hair-styles.

I think the other big thing for me to practice with her is my freehand proportions: for some odd reason whenever I try a dynamic angle, I just make the head bigger and it doesn't really work.
Does anyone have any tips for that? I'm really struggling to wrap my head around it!

I am painfully aware of all of the faults with this piece, but like I've said, it's for practice (It doesn't stop me from being disappointed though...)
