Having a go at a Marvel Spider-man Cover

Ok, so I've always wanted to do a comic book cover. A few days ago I had a crack at a Spider-man Iceman issue that I have at home. It's all pencils and I may change the "Iceman" figure a bit, but it's mostly how I want it.

My backgrounds were never anything special (as you can see), but I will be working on them from now on. And I will be working on my, uh...(oh God...) ... inking too! Actually I'm working on lots of things (um, composition, proportion, perspective... all those handy little things that my teacher in school told me about and I didn't listen to because I thought that art had nothing to do with comic art!)

So any pro artists looking at this will have to forgive me for my mistakes. When I say I'm self-taught, I mean it.
