For my professional practice class with Dave Groff, we have a required sketchbook with double page spreads. I think I'm actually pretty much done with the requirements of it, but I'm probably gonna keep doing it, cause it's major fun (and it's what I actually normally do with sketchbooks anyways).
So these are some of my favorites. Some of them have themes given to us by Groff, such as "I ate this today." Also, I will probably digitally color some of these at some point. But that's a half-hearted probably, so we'll see.
