The main cut shouldn't have been motion blurred; it didn't have to be left plain, but making your main picture blurry isn't the best idea. The background is rather plain; maybe you could have tried mixing a few filters. Your pixel text also needs to have the antialias taken off so it's clearer. It's not bad, though.
Ooooohhh, a women that knows her way around Photoshop.
Anyway, yeah what they all said basically. The background needs something. Whether it's color, or effects. I dunno, but it seems too blah. The main cut shouldn't be blurred, or so overly blurred. The blended cut looks fine, but maybe make it a bit larger so the graphic doesn't seem so open or bare.
