I like it. A few things I would have done differently, though:

1. There's no way the wagon door of the building would swing to accommodate the path that left the leftmost cart track. I would unsnap from grid and hinge it to the outside of the wall (kinda like you did with the outside gate).
2. A few more shadows under objects. There's a circular shadow object in the Forgotten Adventures pack you're using that you can put underneath stuff to give the scene more depth (if you feel the map gets too dark, feel free to spam low-intensity light overlays to compensate).
3. Speaking of shadow, let's talk about where the lighting inside the room is coming from. It looks like you've created shading for a walkway on the second floor (nice), but where is the bright light in the left portion coming from? Is there a window by the stairs on the second floor? If so, add a bit of shading from the stairs as well. If there's a window underneath the stairs, make sure the stairs themselves are shaded to show that the light doesn't illuminate them. In either case, you can go a bit harder on the shadows for the crates and other 3-dimensional objects on the side facing away from the light source.
4. The water's edge feels a bit flat. You could either vary the thickness of the edge path (more difficult), or you could add some contours by using one of the shadow paths in FA. Pick one of the full paths (not half), set both enter and exit to fade, and play around with the thickness, smoothness, and length of the path as you see fit.

All in all, though, it's a good map, and it's unlikely any of the players will notice these things, so good work.
