its alright..jus simple as hell well looks simple...and plain. you could a did a lil more with the bg and still have it nice and clean and spacey as it is.
Darken it. It's way too bright. Darken it noticeably, up the contrast a bit and add a proper light source. Also, if you're going to repeat the image, erase the text. I can see the 's' and the 'h' and they don't really need to be there.
Lightning looks a little washed out, this may have been the direction you were going in but it is all too bright. i like the effects, from what i can see, if you made them spread away from the focal just a bit more you could cover up a lot of the empty space they're all talking about. personally i love the white tags with the touches that keep me looking at it. overall great job!
