I was reading the debate about software vs true art, and i gotta say, the credit goes to you and not the software programmers. Although you gotta love em for making them, what you do with it is up to you. And what you've done with this is great. Good job.
I hate it when I have several versions of something and I have to decide. Never easy. Even though I haven't seen the others, I like the one you chose. Nice variation of colors and fun shapes. Nice job.
