The piece looks very interesting and could be even better if you optimized it, such as using a scanner. If you don't have this available to you, check out Jazza (who is on newgrounds) and he has a tutorial on his YouTube on how to optimize with a camera/mobile/scanner. Due to the quality its hard to see how good the piece actually is, try to make sure you keep 'sketchy'(or messy) lines to a minimum as they can easily ruin good artwork. Keep working and I hope to see your works optimized in the future.
