I like this map a lot.
The overall theme of the map is very creative and well executed. The cave part in particular has look that I might take as a basis for a future map myself.
On to gameplay:
1. The distance between the main bases could be little longer/the map could be maybe 10% bigger in general. Other than that, the general layout looks good. Looks like potentially another good replacement for EI. In particular I like that there are lot of valuable creeps/points of interest in the center that are worth fighting over.
2. Creeps and itemdrops are generally ok, but not perfect. Again, while the itemdrops are on the stronger end of the scale (but still acceptable), there is a tendency that individual creeps dropping the items are quite weak and can be sniped easily. As rule of thumb, I would recommend that lvl 3 items should be dropped by lvl 5+ creeps and lvl 5 items should be dropped by lvl 6+ creeps.
3. The critters in front of the spawn locations will be removed upon the start of the game.
4. Not sure what to think about the tree line behind the central mines. They can be destroyed (as I assume is very an intentional feature), which I like but cannot predict what implications it will have.
5. As stylish as the waterfalls are, they are distracting if fights are happening near them
Overall, a very good map. Approved.
