Finally, I had time to look at those screens. Not that they were still to big or anything I just have been busy and... forgot.
Anyway, your maps tend to go for realistic, or relatively realistic so my only two comments presently are this:
Japans mountains and rocks are much to young to be so rounded. The peaks and canyons would be much steeper assuming this setting is in Japan. I would try to make the rocks more severe and jagged if possible.
The flooring. Most notably the broken pieces are much to thick. Floor boards are at most 1/2 inch thick. Well I only know about American flooring but I assume that its fairly approximate everywhere. You look like you have a bunch of broken 2x4's laying around.
Wish I could say more but I seem to have better feelings for maps from the inside. Screenshots do not really show a map well because the author tends to show the best areas in them.
