@Cashmere - One thing that jumps out to me is that in your first map, the stone tile you are using is a floor tile so it throws the perspective off for me a bit. However, I think you make it work on the one building on the left where the braces on are on both sides. I think if you made that uniform on all the buildings, it would really help. Also on buildings where you have to use shift-click or use tiles from B-E, you need to be sure to go back and add shadows to the right sides. In the first one, shadows falling onto the crates and things on the right will help add depth. Same thing in the second map where you have the sections of differing heights. Use the shadow pen to add shadows to the right sides and it will do wonders. On the last map, I find it odd that there is a cave like that in the middle of the road. Maybe it's supposed to be a tunnel? It just looks really odd to me. Really, overall not bad though. Adding: you posted your interior maps while I'm typing this, I'll have to come back to those.
Okay, I've been playing around with the new western pack just for fun. Here is a saloon scene where things got out of hand and Sheriff Ralph has had to step in. Now, I know, it is ridiculously bare. I was sticking just to the western pack and perhaps some RTP if needed, to see what it was capable of. In my opinion, it's a great start but for my tastes, it's going to need a lot of tweaking. For example, the red stage curtain needs to be brought down a smidge so it's not overlapping the roof tile. The bar tile needs to be edited so that I can make that left piece longer. I would need to make some tables with clutter on them - drinks, cards, etc. To me, the round tables scream "saloon" but there's no way to put clutter on them as they are. My overall opinion is that it's a nice starter set but needs some additions to make it truly shine.
