First off, awesome tileset thanks for sharing it! as far as suggestions I’m more excited to see it come together in your vision but two things that crossed my mind playing with it were
A) expanding on pebbles and stones, would love a few tiles for drawing worn pebbled walking paths (same idea as the paved one but more subtle, rugged and less refined - more so for a village setting than the forest) that feels poorly articulated so heres an example of what I imagine
B) as I see ShonesKishana mentioned, I’d love to use this in conjunction with a cave interior of the same art style / thematical series.
Love all of it, it’s a nice original piece - really liking the houses though a modular pack in that style would be a huge hit I’d bet.
