I have to admit, one of the best things about the interaction on this site is the use of photo manipulation tools to offer tips and suggestions on work people post here.
I showed Quang a head I sculpted at Euro Militaire a few years back and he got out a pen a drew all over it! Focused me on the symmetry of th piece etc. Great that Photoshop allows for the same constructive advice, and keeps your model pen free! :lol:
And judging from this, it can complete your sculpt for you as well.
Fine points, Quang
