Nice!

I like your style. It does what it needs to.

One point, I do feel like it would have been more rounded if the numbers were all the same colour format. You can go dark with light background, or light numbers with a dark surrounding colour, which I prefer as the dark with light is sometimes hard to get right. Or you can go the round icon route with the number on it. There are quite a few options actually.

Still, a nice decent map.
