i know avatar is too big and same with sig, i just couldnt remeber about the demesions. also snaf i know about pixal2life, i usually go to bluesfear.com, and for some reason i couldnt get feather to blur, but meh, ill get them looking smaller and better...hopefully.
when making a sig, try using a uniform size, and avoid Irregular ones. Try a size that goes by 50's, so for example, 300X100, or if you want to push the limit, 350X120. Try not to use the full 500X120. Large, doesn't always mean better.
