Not quite what I was referring to.
Here is an example of good dithering, called interlaced dithering:
Here is an example of bad dithering, which creates single pixel noise:
The other issue is that the dithering technique is not used in the Time Fantasy tile-set. The result is that the house doesn't match the style as much as it could, if let's say a non-dithered shading technique was utilized. However, it is the right resolution and the saturation matches fairly well so it's not a horrible fit. Give it a darker outline (such as seen in the trees) and it will match a little better. Best of luck.
