Very cool!
I absolutely dig the classical look to these, they look like something straight out of the human campaign in vanilla Wc3, and I mean that as a compliment ^^
The tile-work especially is very neat, few people know how to properly work tiles with elevation of textures and mixing colors to blend in a wonderful palette of terraining and even fewer people know how to appreciate it, but you are one of them. (at least the former

)
My only nit-picky suggestion here would be to invite a little chaos into the mix, your terrain so far looks very orderly and precise, almost a little too pristine. I can see that you added more smaller details from the first to the second batch, and while I do think this is moving in the right direction, I still think these details have a little bit too much of that 'spaced out evenly' vibe to them. Like, maybe add some destroyed fences, maybe bunch some doodads more together in certain areas and spread them more out in others, etc.
Honestly though, you're on a good track here, so just keep doing what you're doing and I think this one will turn out great!
Good job
