An unusual view.

This interesting angle on the creek is nicely framed by the dark form of the tree, with its soft foliage and gnarled roots. The water is still running in the creek, despite the snow - at least, I think it is, by the texture on the surface. I'd expect ice to be a little smoother. Often reflections look indistinct and there's the temptation to sketch them roughly, but they give our eyes a lot of information, so make sure that even if its a quick sketch, they are reasonably accurate.
