Forums → Art, Music, and Writing → My first serious drawing.

Background:
I drew this in 45minutes during math class which is why it is on graph paper. I'm not in any classes for drawing, or even an art class. Sure I doodle every so often but nothing seriously like this. I did not trace it, I DID draw it. It is a copy from the album Plastic Beach by the Gorillaz. It seems i'm only able to draw well, if i see it. I'm not able to draw off the top of my head, any tips on doing that?
