Its A pretty nice banner if you ask me. And ya i think the motion blur wouldnt have looked good. The pic cuts are awsome but the text is'nt placed right. I Think you should use some other font. If you want the HBK Font then you can ask me for it. Well thats about it. I think it deserves a 8.5/10. Work On It.
I quite like the stacy one. It's simple but has a nice look to it. The text is a bit plain, as is the banner on the whole. Stacy looks cool on it.
One thing I'd recommend is maybe bringing some type of pattern into the foreground and blending it over the top. (like a bgin the front ).
As for the HBK one, the text kills it a bit. I think it's a good start for a banner but needs to be built upon. Again, I'd rocemmend something infront of the pictures and maybe adding a main cut as the focus of the banner.
