I really like your marquee image! The CP is real cool too, think I'd ax the little images and just go with the larger semi-transparent (X-men?) ones. But that's me, the side art would be a bit too much for my taste too but it looks all right. Guess you'd have to decide where in house you are going to put it and how well it'll fit in/stand out, depending on your objective.
Would have to agree with Unclet's button color observations, that's the kind of thing that, after someone points it out, will haunt you for years, everytime you look at it.
Otherwise, it looks like you've spent a lot of time working on this and you will no doubt enjoy it almost as much when your not powered up and playing games on it.
