The others kind of look.. amateur-ish. For example, the different fonts on #3, that aren't even incredibly good. Also, the colours are kind of.. dirty. Try blue and white, rather than blue and black.
It looks very plain and amateuristic, the colours, text effects and images you're useing in it doesn't make it attractive to look at, practise alot with those two things and I'm sure it'll look heaps better!
I'll stay in touch!
