Dude, I'm just a Photoshopper. Been doing it since the software was invented.
You would laugh if I told you the neanderthal software I used, point being, the program is irrelevant. If you wanna know how I did it, you can send a PM and I'll break it down for you.
It's just what I do. Some of the oldtimers here know I can pretty much portray what my mind conceives.
If you wanna see more of my chops I have Flickr, Photoshopcontest.com, Worth1000 (very, very strict competition) Stock photo... you name it, oh yeah, and about 3 Photobucket accounts full.
