What romlam said. The flare needs the most work. Aside from that, I think it's all a bit too fast. You have seven different 'scenes', I think you should slow it down a bit and go for four or five. I'd get a bit more 'angle action' going on as well, looking across the logo with some more depth of field goodness, rather than the more straight down and looking straight at the text kind of feel it's got going on now. The texture is nice.
