Whoa, Gromit. i haven't seen that one before, nice idea! A few stray additions to the suggestions... i believe Picky's tutorial--or someone's--said to never use dodge or burn at more than about 15% opacity or you get funky results. Very true! Xurge--if that were my render, i'd go back and redo the lighting and re-render, because it's much less work. :^) Over-dodging or -burning will lose the detail in the highlights or shadows--not good, usually. i think i would have used Levels on that one before i started in with the painting tools. Another rule of thumb for Photoshop and post-render touchups--make the software do as much of the work as possible, only paint in when you absolutely have to, and only at the last. For things like mesh breaks--well, we're all SOL there. Must paint them up or better, use the Stamp tool to retouch.
