Your map looks VEEEEEEEERRRRYYYYYY good for a first map, both thumbs up !!!
But I definitely agree with SoUlFaThEr: you mustn't make the windows so close to the corners. It reminds me of when kids start drawing and want to draw their house: they all make a square (with a triangle on top of it) and the windows are inevitably 2 little squares on the exact top left and top right corners of the house's bigger square.
