I've been practising textures. On a heavy book board, I spread some light molding paste. Then drew some lines in it. When it dried, I sanded some rough patches down, and painted it with acrylics, rubbing then in and off until I had the effect I wanted. A little photo was glued on, then I gave it all a thin coat of wax. Finally I added the lettering.
I've been watching the Michelangelo series on BBCWorld. I thought it was well done, presenting the Master, warts and all. And it was very inspiriring.
