Too many unbalances.
on bottom left there are two minerals, on top right there are four.\
There is almost no room on either starting base to build. And i don't know why but you spread out your minerals for some reason.
When making maps, you should:
Make 8 mineral patches in a starting base.
around 6 mineral patches in small expansions.
and 8 mineral patches in strategic expansions, like the middle.
Make it so minerals can mined efficiently, by placing them as close to a startlocation as possible, smae goes for gas.
Try to make equal number expansions for each base, and equal distances and sizes as well.
Otherwise the map will be playable.
