Beautiful map. The style and colouring works very well; your rain is a great success, as are your puddles. The map is very clear. Looking forward to see more of these.
The only thing not working for me is the door and window into the structure in the upper-left. Firstly, although I can instantly distinguish between the door and window, I know that one player in every group I GM will get mixed up (honestly they are hopeless) and have no idea. Secondly, it's too white in relation to the rest of the map; it looks incomplete. Even shading these opes a very pale brown would allow them to sit in the map a little more naturally.
