A Review of Blue background for website by William Valencia

It has some dimensional qualities, add some type and graphics and it might start to look cool.

But if you want it to have more depth. make the bigger circles more opaque and let the smaller ones start to fade a bit. Start over from scratch and create one or two big ones, a few more mediums and the fill in with various smaller sizes.

I've seen tuts for this kind of thing out there. I just don't remember where.

Good luck.
