Two more of these work sketches. The top one is of a coworker, done rather quickly with just reference, no marks. The second is a somewhat unsuccessful copy of a Hals painting. That one had some marks but I think it's a poor choice to copy as there isn't a lot of structure in the original painting and he had access to the real person while I do not. Or I just did a crappy job. That being said, there are things I like about it and still think painting on the iPad is a good bit of fun.
