I honestly dont like this. Just some of my thoughts on it...
-Your background pictures and your foreground pictures are not seperated enough. I mean, your foreground picture doesn't stick out of the background. Sure, it's bigger and what not, but there's nothing to make it stick out, so it just blends into the background. Maybe give it a more solid black, add a very light/small border, change the contrast, add some white, anything to make it slightly different to the rest...
-The background is WAAAAY too busy! There's just too much in it to really enjoy it. From first look it seems you have 3 background pics, but at closer look you have possibly a fourth? Too many, imo. Two, absolute max three. There's just too much going on. Possibly slightly better choice of pics, too.
-The colour scheme is good. Contrast could possibly use a bit of tweaking - I'd go with more.
Those are just my thoughts on it though.
