RTS game unit redesign mockups

Here's a sample of some redesigns I've made using Photoshop. I usually do quick mockups of the sort to get an idea as to how a particular unit or vehicle would look, and to explore different variations, before handing it out to others to do texturing and 3D modeling work. This helps better communicate how an asset is supposed to look and it helps with iteration, as it means the artist doesn't have to go back and do more work.
