Critique this please? Will probably post more drawings here in the near future too

Hey, this is my first attempt at TWO things; drawing with a tablet stylus thingy, and drawing with colour. Seeing how they worked, I decided to try for a new style.

The drawing is of myself. Referenced by getting the most important lines in a picture I particularly like, then decided to just mess around with the combination of colours and stuff.

I think it looks kinda bad in a thumbnail, but quite nice when blown up. Well, that’s just my opinion of my own work.

I just want some feedback on some of my work. So…comments? Tips? Criticisms? Anything good? Bad? Like? Dislike?
