Could have at least taken some pictures in-game instead of editor :P
Also, one thing that bothers me about those castle tiles are how the bottoms are diagonal and the tops are sharp corners. It seems inconsistent, yet is done all the time.
One thing I might suggest for those stone path tiles, is that instead of using alternating color swaps, instead just change the color of the "pebbles." Like so:
It's a bit more subtle, yet accomplishes the same effect, than what you're currently doing. I wouldn't use my colors, though, as they were just picked somewhat randomly so the effect is pretty strong.
