Man, that looks really good. The only thing I would suggest doing is to maybe motion blur the texture to create a more gaseous look for the surface and adding in a few black splodges to represent sun spots. But other than that, it is a fantastic piece! Did you learn how to do this from Ultimate Planet Tutorial at all?
This is beautiful.Well done mate.
cool looks like mercury or venus actually
Thank you. I like to think it's a sun, but I know a real sun would probably have more sun flares.
Looks good. Kinda reminds me of a skin cell.
Very nice work !
