I've got a thread like this on the official forums and I figured I'd start something here offering my assistance to any who want/need it.
My only request is that if I make you a sig please don't link directly to the image instead upload it to an imaging hosting account of your own so it doesn't eat away bandwidth :)
Some examples of my previous works.

I also do avatars and wallpapers as well.
