Happy Bidding And Thank You.

may i recommend that you MAKE THE IMAGE in 1024x1024 format with a VERY small brush then resize to 128x128 , because that is (no offense) SHIT QUALITY...

i work on 1024x1024, resize after and the quality is IMMENSLY better .
hope this helps.

^Erm... No it's not. If you resize it down from 1024x1024 it will lose a lot of detail. It just needs some anti - aliasing.

Lol to HiM999, I wasn't even trying to make this nice. xD
And what does Anti-aliasing do?
And, It loses some quality when it's put into POV-Ray and even more when made into an "optimised" gif..

Like merges the colours and makes it all less harsh on the eye and pixilated.

Hmm.. when i did it in GIMP, there wasnt much difference just added a bit more silver pixels here and there..
