It may sound silly but mapping wise it looks 10x better. You can convey the message of training space without such a large space. You have a bunch of negative, unused space.
Example. Its a store room. There isn't a lot of unused space and everything looks crowded. It looks like a store room with a bed.
Its not a very good village but look how i try to kill that empty space. I try to fill it using the least amount of different colors to try and create a cohesive and somewhat busy map.
I tried to do a dojo. I added some weapons around and made it smaller.
Its silly to have a bunch of space with nothing in it and it is not pleasing to the eye. I understand what you are saying, but smaller is better in mapping. There is nothing going on in your maps.
