Hmmm - not too impressive. While the background (that sci-fi metal marble thingy) is pretty good the rest somehow has little "love" to it...
The "Lord Lemmi" text looks sort of cheap and the stretched OTA logo also looks wrong (due to the stretching). That "Battlecat" in the middle is sort of nice but imo it's a bit displaced there as I have no idea why there is a cat on the logo. Then there is this metal plate (You took it right of from MapZone didn't you?

) on the left and right which seems to be there just for having some different metal-like placeholder. But as its intention was the use as texture it doesn't really fit here (with that said it might even had been a better idea to keep that grey sci-fi pattern I mentioned in the first place...
Then there are those bordered bars with some red/black stripes. While they on their own aren't bad they sort of don't fit into the picture - especially as they form a Tic Tac Toe raster...
So well - what suggestions do I have?
Well maybe you should go for a non-widescreen image which already saves you some thoughts on what to put on those huge empty sides. Then use that sci-fi background pattern for the entire picture and put sort of a symbol / logo on top of it. To give an example: You may want to keep sort of a main logo in the middle of the picture and so use an "X" which you spice up stilistically by e.g. creating that "X" by to "arrows" that point to each other (don't know how to really describe what I mean) or something else...
I think you also shouldn't use the OTA logo but only something for your own mod - at the most you could use some of those Cavedog unit renders if you see a good spot for them...
