Well, I'm new here and one reason I wanted to join was to post some of the graphics I've made related to SC2. At this point I've only made signatures for on forums, but I could attempt some wallpapers or banners. Sorry if this isn't the proper place for this topic.
Feel free to make use of these and/or request a new SC2 sig. I imagine I can throw together a couple more if you post a couple specifics of what you're looking for (such as text, a picture to use, coloring, etc...).
Yes, I know the Marine one doesn't have that many effects. It was tough because there wasn't much to work with. Bottom two don't have very impressive text, they were the first of the four that I made.
Hope you enjoy
