Nice lines, nice style, cool use of purple and light blue.

Just a tiny nit pick from me, one of the dots in the background is not symmetrical to the other side, *on the right hand side there are 3 dots in a line and the middle dot doesn't curve around the shadow*

like I said, that's just a tiny flaw that i happened to noticed. even if it was fixed i still would have given this a 4.5, always room for improvement.
