If I made it bolder, then you could tell how crappy it was. ^^;; More importantly, I only did one set of shadows/highlights, and I think if I were to make it darker, it would require another layer, or at least more feathering.

I dunno, I guess it's hard to tell if you haven't seen how flat the original looked. But you should have volume 8, so you can see for yourself. ;)
