This reminds me a lot of old Fire Emblem maps for the GBA games. The warmer, slightly darker colours of your tiles are a lot easier on the eyes though. They would be excellent for use with something like the SRPG Maker.
Would you consider making more complex mountains like so?

Either way, I'd love to see more stuff like this - different biomes, villages, castles, dungeons - in this kinda style!
