actually i like the text the most, but those spheres could use some serious work. their pixelated around the edges, so work on that tecnique for making them. the bg is cool, but needs a little more work, to give it some more contrast, and make it less boring. the border looks nice, just maybe try a 1 px border of a darker colour then the rest of the bg, ontop of the checker border. also, i dont like the colours, theres too many, and it looks slopy that way. next time try using only a range of colours, like purple-blue or blue-green, or green-yellow etc.

keep working at it though!
