well, as for now, Unreal Software got a comic look, representing fun; your banner is more with black colors, can be used for darker profiles, however, I guess it will have no use here as he'll have to turn over the whole page.
You should have used png format + transparency.
Now the only way to use this is using a white background or cropping the image manually :S
I agree with that. PNG with transparency is needed. I also think the logo looks quite epic, futuristic yet a bit grunge looking. I'm amazed although it's in a compressed format, do you have the original logo in png format? if so show us.
