This is what I have came up with after a morning(for me a morning) of searching and expirementing with gimp. This biggest problem a had was to make some of the rocks seem at a higher elevation than the rest so I used bump map on them.Well I'm not that happy with it so if you have any other ideas please tell me.

P.S.I don't care if I have to draw again all of the rocks cause it was quite an easy procedure.Also I think I have to read the gimp manual's entry on bump map.
