All the detail work is nice in the roof, but it takes away from the 3 dimensionality to it. Detail lessens in the shadows. Theres some non pixel art stuff going on here, I don't know if you mind, but it would greatly reduce the amount of used colors if you fixed that. Also, you've made the rocks " pillowy" when they are a nice opportunity to break up form into flat planes
Hey thats some awesome feedback, really appreciate it.
I get what you mean about the lessening of detail - that works really well so I am going to re-appropriate that back into the work.
The rocks are meant to be paving stones, not rocks, so obviously flatter for that reason. I do love the rocks you've made tho and I will endeavour to use a similar style for actual protruding rocks elsewhere.
We do some under some criticism for the shadows causing too many colours. Unfortunately, the way we tile the world in the game requires a separate image for shadows that are placed over adjacent tiles in a way that we can never determine exactly what they will be over. Therefore its been easiest to just create a single transparent texture and deal with a little bit of uncleanliness
