Hitch Hikers Guide cover

This is my latest project at uni - we were each provided with a book at random, and thankfully I was give The Hitch Hikers Guide to the Galaxy! We were asked to design a cover for it. I decided I didn't want a cover that would give away too much, so I've made it slightly ambiguous, and hopefully people would look at it and think 'what the hell is going on here? I'll read this!' It does of course feature Arthur Dent in his dressing gown, as well as one of the mice that want his brain. ;D I thought I'd show him as a silhouette, as I didn't want to ruin reader's mental image of what he'd look like, and leave it open to interpretation. (btw, just in case you don't know, the fish border refers to the ever-helpful Babel Fish! If only they existed...)
