/ic/ - Artwork/Critique

I'm pretty confident in my own self-criticisms, but I could use some advice on how to proceed.

This is the first (excluding a few aimless sketches) drawing I've done in almost a year. I feel I've retained some skills and completely lost others. It's easy for me to see where I went wrong on this one so I can do it better next time, but in terms of more global practice, I'm not sure what I need to work on. Poses, color, certainly.

I guess my question is, is there anything about this that's just offensively bad, or would my best course of action be to just keep doing what I'm doing?
