Woah.. I wish I was as good as you at digital editing.. I used to use Photoshop alot before to make random images, but none of them were any good at all. Just cropping some Anime character out of a picture and putting it on some background I found on the web.. And sometimes I wrote something next to it and I found it to be really funny. Though I always wanted to be able to make some really nice things like you do!
That leads me to a question, do you use Photoshop?
Also, how do you soften the edges? Like on your avatar picture. It looks really good!
