Playing and twisting lines. Black and white, gold and grey. Plus gold leaf. A bit of collage too. Its a bit of fun, different ideas, not sticking to one style. Using contours and texture to get different ideas across.
One thing I do tend to do is draw profiles or three quarter portraits facing left. I discussed this with other artists a while ago. It may be that right handed artists draw left facing profiles and vice versa? Is it something that’s ever been tested?
