If you want, check out some other stuff on my deviant art that I was too lazy to post here.
Edit: Btw, I know I haven't posted in a very long time. Good to see the competitions are still running, and WOTW is on number forty-something now after I made the first one long ago.
A mixture of clouds, clouds with displacement, and dents.
Speaking of displacement, does anyone know what plugin pack it's in? I was looking for it so I could link to it in one of my tuts, but I couldn't find it.
This isn't really the forum for asking a question like that. It depends on the background... you should make it as small as possible so it doesn't load slowly, but still make it look nice.
