I like simple and fresh too and these look great. But yeah, I have been playing around with the designer a bit and it quickly gets overwhelming when you realise all the possibilities. Even if it is just a simple design, there are still endless possibilities. Going for just a single colour, like @ranfan's blue Spartans, or indeed your clean and clear design here, works very well too!
And once you start messing around with graphics in Photoshop, it can soon become an addiction... or as some call it, a folder called CIEM Design Ideas with 14 sub-folders inside...
