The rains are coming

This started as an attempt to speedpaint a landscape without reference, because I've wanted to try that for a long time (I had never tried to speedpaint a landscape with or without reference before, or indeed painted any large landscape, except for this one: [link] where the landscape is more of a background than a main focus). I ended up spending about 8 hours on it, and I'm fairly happy with how it turned out, and that I'm able to do this without a reference (kind of thought I would fail horribly, haha). It was fun to paint and learn from ^^

List of things I want to improve at based on this piece:
-lighting
-perspective
-clouds
-painting faster
-everything
