I would look at playing with the height of each brick. It will add a lot of depth that you are currently lacking. EDIT: Should mention I meant in the Zbrush sculpt not the low poly. Sort of like this:
--EDIT-- New Project: Final texture: --ORIGINAL POST-- Testing out some hand painted textures.. I would love some feedback on this. ps: marmoset: zbrush: I feel like this would be the base that I would paint over, to give it more of a painterly feel, but I'm not sure where to take it from here.
Nice sculpt, but I think that layered rock is a little to high. I'd do is more decent next time, since it looks kinda odd, Fanny did it more decent in her tutorial, I guess. But I really enjoy those little details you added.
I'm not really even done with the sculpt, but I really wanted to test out the zbrush to game res workflow on a piece like this. Just a simple color block out with AO overlayed.. nothing even close to final yet. ps file: maya game res: The game res is just under 1000 tri's. Not really sure what a good count is on something…
