This is an excellent example of TEXTURE. When you look at this art work you can see the sharp, pointy ends. In your mind you can imagine what those pointy ends would feel like -- looks like a Dahlia flower
Texture - ✞When through the woods, and forest glades I wander, And hear the birds sing sweetly in the trees. When I look down, from lofty mountain grandeur And see the brook, and feel the gentle breeze.
