To start off, I have no clue what the theme is on the server you are on, So I'm rating this based on How the tiles are
used (Especially in iEra/Era).

The top of the windows (shown in Green), are just so confusing in my opinion. This seems to be your style which is nice, however I just feel like your execution is incorrect.
You need to take things slow and not make it look like there's too much going on.
The parts in brown/red signify that you need to link the Lining borders together.
The parts in yellow indicate the execution is wrong. Notice how you take the wall back one, yet you don't do the same to the border.

This level is literally a flat house.
The reason is, you've added no tiles to represent the roof slanting down (on the backside). I've indicated where you need to add the tiles.
Also link some of the adjacent roofs together. The level walls seem very repetitive. Variate your design a little.
