For those who know Shadowgate i have news, there is going to be a brand new remake.
If you don't know it, it's a classic fantasy adventure game which was originally developed years ago but is going to re-emerge now. The graphics will look very painterly, the entire environment consists of artworks and animated sequences.
Here's another signature I made for a friend on WoW using Photoshop. It's a Human Female Mage in Tier 5. He requested a red a black color theme, but since it was a frost mage, and I wanted her casting a frost spell, I saw it fit to put some blue in the backdrop as well. I think I did a good job of getting the blue in there without it detracting from the colors that were requested.
As with my other signatures like this, since I upload them as jpeg's it gives them a white background, just keep in mind that the white 'background' should be transparent, and is on the .gif file.
