Lin, I love the perspective, values, and negative space. Great composition! Please include size and media when posting. Members want to know as much as possible about the art posted.
You can also post the work under the media, like acrylic, and topic. You dog paintings would make a great thread in the Animal &Wildlife forum. So many members will enjoy them!
We were posting at the same time. Really like the motion in both of the others. I glad you posted them. I didn't see them when we met.
