I have recently been wondering, "What program should I use to make fan art?" I am currently using Paint.Net for my feeble attempts at making fan art, however I do not know what program I should use, and exactly how to give it the correct atmosphere, for example, currently with Paint.Net, I am inable to use browns and make the dark colors of the Necromorphs from Dead Space.
Basically my question is: What program should I use, and how should I go about doing it?
