you need ground tiles that have shadows where the house meets the ground(for the front of the houses). there was one other comment months ago mentioning how the houses looked chopped off at the bottom, the lack of shadows here is why. other than that this set is perfect. even without this fix, I'll be buying this set, but it would be nice to have.
you created shadows on the front sides of the house roofs - this is exactly what's needed except on the grass/dirt infront of houses.
should be relatively easy to create some shadow sprites for use in Tiled that go on their own shadow layer, so there doesn't have to be any modification to other tiles, and we can throw the shadows on the right places. Should basically be three shadow tiles, two corner/edge tiles and a middle tile.
Thanks for clarifying that earlier comment, not sure how I got down the track I was on and see the issue he was describing straight away now.
I don't have plans to amend this set at the moment.
I agree that the bottom edge of the house tiles could use some more breaking up so it isn't so jarring, although I wouldn't personally use the solution you described. Still, you're welcome to make any edits to the set as you see fit.
