Ok, so I finally got my butt into gear and posted this picture that I made a few weeks ago. I must say, it's the best thing I've done yet. and, just so you know, I drew this on my computer, completely from scratch. No kidding, I drew and blended everything (other than the wings, they were a brush I had)by hand in a matter of 5 hours. Yes, that is a long time, but hey! I was being a little persnickety about the blending and the background. At first I just tried to use layer style, but when I did the leaves by painting, I decided I had to do the rest by painting. I didn't like the look I had originally anyways. So, now I have this!
So I jut decided to post this up. I don't remember how I made these photos I just found them on my desktop a few days ago. Anyway, I like the first one Because it's a ring of fire, and I remember using the smug tool to get that look. I don't remember how I got the ring in the first place, because I've been trying to make that again. 
Oh well. The second image is probably a circle that I used the block filter on. And the last one is something I figured out how to do a long time ago. The only thing you use is the gradient tool set on difference and have the grid turned on so you can get it even. That took me a long time to figure out. Anyways, you can also use different colors, but pick the opposite color so you don't end up with something weird. Also, it depends on your background. 
If it's black, it will give you a separated look, but if it's white, it will give you a connected look. I think I'm going to make a tutorial for making them, but it's not that hard. Anyway, I made it black and white but I colorized it, so it was blue.
