Okay - so I may not do this every week - but it's a good goal. This one took two evenings to create (I either draw or make trolls while we watch tv). I use a simple mechanical pencil (nothing fancy) and a pencil-shaped white eraser (it comes in a plastic dispenser thingie) on a nice drawing pad - paper that has a tooth to it. I sketch lightly, then go in with harder lines. I erase a lot. Then, once I have the drawing down, I start shading. I probably could have pushed this one even further.
Now I've got it in Photoshop to color. I'm trying some new techniques, fiddling - fiddling. I'll show it to you when it's finished.
