Great stuff. I have tried this before with unsatisfactory results, but I didn't tighten the skin to the hand afterwards. So that is an extra step that I was missing.

One additional question though - when you are pushing the skin of the arm in, how are you doing it without affecting Michael's hand? One of the problems I've had in a situation such as you have depicted is that I will select Victoria's arm, but when I start painting with the morph brush, with Michael's hand in position, then it morphs Michael's hand instead of Victoria's arm.

Also, a suggestion for everyone. If you compress her arm too much, or too far out from Michael's hand, then you can use the "Restore" brush to undo what you have morphed. Instead of trying to use the other brushes to manually recreate what the arm should look like. The restore brush will simply undo any changes you've made with the other brushes.
