I'll try and help you as you helped me soooo much also your not heaps bad the forest one looks alright . Hope you take constructive criticism cos I want to help
First off the wooden thing going down I find looks best on the corner of the wall like this
where you put it in middle.
I'm not a fan of tight areas but yours are a bit too big most of them could be halved in size . How often do you see a room or same floor with just one big room in wide area? Also in first room upper half of wood is really light rest r dark? are you trying to get light from the windows? I don't bother with this as I use blizz's DNS and wouldn't look good for me but you should check out how Calintz does it as the small windows wouldn't light up whole room
A lot of pple don't do this but I find the carpet should go a bit under the wall tile I mean you can walk there so you're walking on wood that means here's an example.
And the stairs on first pic they look like they are going upstairs but must be going down because of windows ect and no exit so change it to this
Here's just some maps both took me like 10 mins to get the ideas flowing through you.
I won't comment on town as only just started it, but the rainy forest looks good if you wanted you could add little dips in water small waterfals to show it goes down hill but it's up to you also I would try and get a merged tileset more than one type of tree.
