I've been MIA due to too much work, not enough painting! I did manage to get a couple of tree value studies in this week. I was concentrating on avoiding "lollipop-itis", wherein the sufferer manages to make every type of tree look like a lollipop.
This is some type of oak, from a photo. I was experimenting with keeping the shapes big.
Same tree, different day, done with brushes. I think I like the palette knife version better. This one looks a bit like a spider. Very Halloweenish.
