Top house is too crowded, remove the tree by the door. Also bottom left area is too crowded, the trees branching into the middle restricts player movement by forcing them to stick to the little path. Leave the center of the map clear and keep the trees to the edges.
Lovely map! But there's a little space to walk near the top house, you should delete the tree next to the door. Also, I wonder if my new Petalburg house would fit this map And finally, this ugly bench you've used is made by me too xD
