Ah you should have said you reduced it, i made a little example of the door for ya too, i explain what i mean better this way.
I raised it back a bit and i added more to that bar across the door, metal bar is maybe a bit too long though.
E- The bed would look flat even against the wall, i think some darker color to define the folds of the sheet would help a lot.

Loving the original/edited graphics and characters, i really like the look of the female with the red hair too, and the lady bug is an awesome character as well.

I don't know, the graphics of the characters clash horribly agaisnt the blown up seiken densetsu tiles, maybe because the characters are dark as hell and everything else is kinda blurry, ..maybe try darkening the sorroundings or lightening the characters up? Don't know that it would work but worth a try i think.
E- You can also try opening this tileset in photoshop or gimp and sharpening the whole thing up, you'd have to put in some work to fix the little things but it might look better.
