i thought i remembered 'zoso' doing some tiles that were VERY similar to these, but i cant seem to find them.
as im not 100% sure the tiles are yours, i wont bother critiquing, but i will critique the sprites.
the sprites are pillowshaded, and you have to many colors. both of them read better at 2x+ and in the second one, the dithering makes it to messy. try for simpler shapes and adjusting the contrast to establish a top down lightsource.
another issue im having is that the sprites are disproportionate in comparison to the doors to the houses, and there are a few perspective issues (fence, trees)
