Nice work, Nige - very dynamic!
Yup! Cool Prof. Zoom Nige!
You've really got the hang of skin tones and lighting in Photshop now mate, or are you doing a grey shade on the art then flat colouring in PS?
This was coloured in flats, shading added and then the line art colours altered...glad you like the effect, just starting to experiment with this effect (Doc and Zoom being the first!)
