My experiment was, what if he had painted a battle scene from 5th edition D&D ?
I feel this went quite well. At one point I wished that I had painted it in portrait rather than landscape format, since the figures are taller than they are wide, and there seemed to be a lot of surplus space to the left and right of them. But I quite like my shadow-dappling twisted tree, and Colin the Art suggested the addition of a mysterious shadow on the edge, which I like a lot. I feel this painting is telling a story.
Not in art class, I made this :
The center is poured acrylic, so it's very smooth and glassy, and around the edge the roots are made of modeling medium and are iridescent, so there's a lot of texture difference. I am not sure what I think of it. It might be a bit too deliberately arty, and yet not skilled enough to really work? Unsure.
