First of all, great work, my friend!
However, I put some of your images in Graphicsgale and I noticed quite a few tiling errors that you might want to fix.
In the first image, I see tiling errors with the floorboards, mat/rug, and the top left bookcase. Im not familiar with the game these tiles come from but I moved the top right bookcase to where I think it should be placed. I could be wrong about that though, but just throwing it out there...

In the second image, I see tiling errors with the floorboards, table, water bucket and again, the bookcases?

You will avoid all these tiling errors if you use something like graphicsgale to make maps/rooms/tiles.
