Here's a progress shot of a new personal piece. I'm drawing on Canson Vellum (one side the lines, the other side the values). I've also used Photoshop to help move and resize some elements (a little faster but same principle as tracing paper and photocopying the drawing).
I plan to paint this one in oils so I'll be prepping the board tonight. I think I'll make it 16"x20". That should give the bear cliffs and waterfall enough room to feel massive. The working title is "Bear Cliffs" or "Bear Falls". Anybody have any other suggestions?
