Hey WinterWind, I noticed you asked for critique over at the group so I thought I'd see what I advice I could give.
The first thing that comes to mind when viewing this piece is your rough linework - you have a lot of broken lines and there is very little line width variation. Varying the width of your lines can be very useful in giving your work some 'pop'. Varying line width can actually work with broken lines, because you can thin a line so much that it disappears, you've probably seen this being used in the eyes. This is different to simply having the line end for no reason such as around the fingers and wrist/cuff area in this image. Make sure you are confident with your line placement! I can't stress that enough, go over them again and again and line width variations may develop naturally (but obviously don't overdo it).
I like the concept here, it's quirky and interesting - opens up to lots of possible ideas. Keep it up!
