The silhouettes for guns are the most fun for me. Some started as pencil drawings in my journal that I scanned in and turned into clean silhouettes; others I got by just messing around in photoshop with my brushes and the all mighty shift key. These are very sci-fi based, but I tried to make them seem somewhat usable (or at least able to be held and fired; I don't know much about guns, especially sci-fi guns.) Having fun with them all the same.
