Actually I posted this pic on my website, which for some reason is being gay so you shouldn't have to dl anything. And to Pawige, thanks for the input, I think I may go with number four. 

Well it keeps saying "save?" whenevr i click it, and i have to select where to download it to.

Non dither? Ad a lot more different shades of those greens in betwen each one.. that will do the trick. and make it smooth (as long as the colors you use arn't to far apart or you will get obvious lines between to shades, like you currently have)

But seriously. That will make your sprite have way more colors... which isnt good, unless you just want it for looks.

Here is a quick job of what im talking about. But it will take a little fooling around with shades.

I didnt believe that it had that many colors so I counted them myselfI counted 62 colors in the Zidanes(only counted the tail in the second, Im assuming the rest has the same colors) and 14 in the expression bubbles. Most of the colors look so much each other. Some contrast to the colors, color reducin and a different skin tone would help this out alot.

Did you count it by eye? Cause I used the color counter built into Graphics Gale to get my results. But yeah, that was the entire picture, with the bubbles.

Um, the link's not working.

Yes it is. It's probably just your  internet browser.

Can you please resize that canvas? It's blaaaannnk.

Me? I dunno wha tyou mean. I edited my post above though. I removed the transperent backgrounds and resized the canvas they were on. (because they were both on 1000x1000 and neither were that big)
