much better,but there is still some minor issue. like the carpet that red arrow point at.
it could fit in 3x4 of 16x16 tiles. but now it takes a 4x4 tiles.
you can view it in some online tilemap editor like spritefusion. I also recommend sprite editor like piskelapp---- I use them to rearrange resize and regroup my asset a lot.
again, thank you for the fast response!!!
