New bushes and colored rocks

I've got some shadows! They're only cast on the ground layer, but it helps certain terrain types a lot. The shadows are painted, too, lol, but you can't really tell.

I took three different tries at making low brush sets, and combined them in a single tile. Now it works much better! Also, I've painted big/high bushes. Low brush slows movement and can be hidden in with the stealth skill. High bushes also block line of sight.

I tried coloring the different types of rocks. I have mixed feelings about the result. They certainly "pop" better, but they were IMO pretty distinguishable before. I don't really like the look as much. Might try a different set of colors. In gameplay, the low gravel slows movement, the medium boulders also can be hidden in with stealth skill, while the big ol' rocks are impassable and block line of sight.
