1)

I finished the first part of the Mutant Jack project in the beginning of the week.

Then I started the second part and finished it at the end of the week, it's a mix of a gecko, fishing cat, and a leopard seal.

2/3) I picked a tutorial called SketchUp: Concept Drawings with Photoshop, because I've used SketchUp before and I really like using it. So thats why it seemed interesting to me and I picked it.

I think I'm still in the A to B range, because I could've looked up a tutorial to learn how to do some of the things for the Mutant Jack project better, because the way I did some of the things where not done in the cleanest way, and could've been done in a different and more professional way. But I felt it wouldn't have been worth it since even when I try something specific in a tutorial, I usually end up getting rid of whatever I just did.
