Thanks for the feedback guys. Yeah, the strong colors are from me using GIMP's burn effect on the greens cause they seemed a little washed out, as well as the yellow tint I have for daylight. I tend to like heavy saturation, but I can certainly see how others wouldn't.
Shadows: You're 100% right, I haven't touched them yet. I knew I forgot something. LoL.
The cliffs are my attempt at making them look a bit less square like, but nah, not supposed to seem like it's about to collapse, haha, after all, her house is built up there.
The grass spots are basically just supposed to be subtle changes in elevation, the regular grass seemed way too flat and uniform. They're static for now, was considering animating them at some point.
The crystals are a natural part of my game's world, they grow there normally just like any other plant or tree, and can be collected by the player. I figured they may stick out a bit, I'll have to try to find some more natural looking ones.
