hey rabbit :3
i think you've made a good start with your sketchbook. I think you need to keep practicising hard and keep drawing before you can see significant improvements but if you keep the enthusiasm up you wont have a problem,also i reckon i can give you some pointers on the ice cavern (and im impressed you're developing one piece like that) - so remind me on skype tonight.
keep going bud :3
