Seems rather bland;
Okay, so you have nice typography. Thats about where it ends. I saw an ad for your clan with that banner, I wouldn't look at it for more than a second. Scrape this, and start over, keeping the following in mind:
1) What are you representing?
- What type of clan do you belong to? FPS? MMORPG?
- What games do you play?
2) More natural dimensions; the ones currently used are awkward.
3) Color. Black and white, in this case, is b-o-r-i-n-g. This is a clan! For a game! Games these days are all shiny and nice looking, and youre advertising your clan using black and white? Slap some color into that work. Consider working with nice screenshots and some cool effects, or something.
Work on it again, then re-post it. I'll be here
