DarkGamer, the concept is lovely. I agree that the viewpoint needs adjusting. I'm assuming this is just the rough of it? The colors are very saturated (which is great if that's what you're going for) and the black lines stick out. I've noticed, with pixels, colored lines look much nicer. Unless you're going for the sketchy, hand-drawn look? It does look fantastic for a starting point, and I am a huge fan of mushroom houses. =)
Saul, I am in love with your cave. That is all.
Here's another from me;
It's the market district of a forest/mountain village. It's a custom merged tileset and I'm still working out the kinks, so let me know if you see any errors. I have a bunch more maps of this village done, but I'd rather not flood with them.
