personally i like the middle or left, i admit i might be a bit biased though because i'm not a huge fan of lime green and the green in the middle one isn't so bright! they're all nice and colourful though
I really like the left one, though I think it would look better with a darker green. But the design is lovely! The middle one I like the colours the most on. The right one is a little too super mario for me. So I think I would vote either the left or middle one
I like the left one the most, but would like it a lot more if a color other than lime green was used, it's just my opinion but I think red would look nice, but their all quite nice. ^_^
