Otherwise nice, but I don't like how the biome looks like. Currently it reminds me of a wasteland. I think it should be "mystic" with glowing blue trees and flora. Well, it's just my opinion, maybe that is too much for Minecraft But I'd like it the way I want it.
Real Moorland can be a bit barren, but I wouldn't really call it a wasteland. Have you ever seen pictures or video of moors, such as the moors of Scotland and England? That's what Moorland is. It can be very beautiful, but capturing that side of it in a Minecraft Biome could be strange.
These two basically sum up what I'm going for. Those pink flowers are heather and there are moors so covered that all you can see is pink, so I'm working on a spoiler for heather as a biome-specific plant.
