To be honest, there's nothing complicated about it, either. It took me about 10 minutes to do all this. It helps to know what you want to make before you make it. Wolverine was just a couple of grunge brushes stuck over each other, then the orange and purple gradient map took over the rest of the work.

Banners and graphics are all too easy for me, now. I need to start challenging myself with things like animation. xD
