Polygons, Hills and Valleys, and other nature-ey things

...Oh, and a complete aping of Olly Moss' masterful work on Firewatch (What's Firewatch, you ask? STOP reading, and go play Firewatch...). Seriously, if you are like, "hey, that valley looks familiar," it's because I totally stole it from a piece of Firewatch artwork. All credit due to that team!

Anyway, was talking to @Tatiana Bischak about mountains, and movies, or something, and then got to doodling whatever was bouncing around in my head.

The polygon mountain thing looked more interesting in my head - and I also drew some bits, and wished I had done them in reverse tones (the unforgiving curse of ink), but ah well.
Fun drawings, and no drawing...no matter how horrendously crappy it turns out is useless. I always learn something.
