Seriously man! thats genious!
so next question about tilemaps for you then =P have you thought about combination tiles? they are tiles with two diffrent sets on them. for example, water tile and dirt tile, that way when you autotile, and you drag dirt thrue water, it automaticaly adds tiles made to be like a sandbank or however you set it up =P youve kinda done it in therpgmaker tileset for grass and dirt and water and dirt but id love to see you expand on it :3
oh and have you thought about adding "random" tiles? its just adding something like a few grass tiles with a diffrent look to them, like grass in diffrent types or small flowers.
like this image. everything thats not dirt, bright/dark-grass is "random" tiles. belonging to said sets. it gives a completely diffrent feeling of life to the tiles :3
