Landscape 01: a meditation

Landscape 01 is a meditation on the tree-ness of trees. It's also the first thing I drew on my new iPad Pro. First time I am working on a tablet, too. Nor have I done any "art" since I had an art class in middle school. My photographer's eye can see the horizon going askew, something I usually don't mess up with a camera. Is that a pond? A stream? A fen? Those cattails: not enough or too tall? I should consult photos of them.
