Ballerina - sketch

Can't focus enough time to do something elaborate, and not wanting to use reference images is really bringing me down. I have 2hrs of art each week, and it drains me of inspiration completely, but I guess I'll have to use references in the future, because I'll never be able to advance if I don't. Such a conflict was this than a wondered a bit these few days if I was willing to carry on with photoshop... or just stop. But I won't quit, not just now.
