To be honest this is a gorgeous map - the small details, water, cherry blossoms, and sense of place - all of it. This map is currently serving as an inspiration for my KotH map layout (currently hoping it will not come out too similar). The custom models, too, are excellent - maybe I'll pitch in a request some time for the highlands/alpine theme I'm working on down the road.
If there had to be any bits of constructive criticism, I noticed that the side bridges leading to the point (the ones with the stairs immediately before the center tower) appears a little awkward to enter. What I mean are those stairs - it seems like there should be a little "landing" between the bridge and stairs so players aren't running up the side of the stairs to get into the point room. A nitpick, I know, but that was the only thing that stood out. If through testing it wasn't a problem, then so be it - this is mostly a visual thing as I'm sure players can enter the stairs regardless.
Great work, looking forward to playing on it (I'd love to see a KotH version, but I digress).
