Layout (feedback please)

Hey guys. Ok, so this is my latest idea for a layout of the markers. I'm having a difficult time coming up with a cool way of presenting the markers I've made, but I personally think that this could be a nice way of doing it.

I'd love to get some feedback on the layout, colors, title etc. Is there too much or too little space here and there. Title? No title? Anything you might have in mind when looking at this. Thanks :) I'll be selling it on http://society6.com/JOMANI once it's done!
