5 Wacom Sketches

We had to do 5 sketches digitally on the Wacom Tablet. I'm starting to get used to it, but it's annoying when I keep pressing the button on the pen and the little menu pops up every time. I forget to change the brush size and stroke, because I was in a hurry to just get them done, I didn't want to mess with them. I only changed the stroke and size of the brush on the tree sketch, which is the one I like the best. The koala bear was the first one I sketched, so it's not good. It looks like it has bangs which was suppose to be its darker fur or shadow. I traced all of these images.
