I've been switching off days lately of drawing and painting, and I've also started using micron pen for my drawings rather than pencil. It's been a good change for me a stretch if you will, When I draw I rely on shading but with the pen and ink it's always the same shade and so I have to figure out different ways to accomplish the same goal. It's a good challenge for me, gets me out of my comfort zone. I've been liking the results so far.
