[sub]I think the correct way to handle 'mineral-starved' is to add maybe another real expansion on land, not place random mineral tiles around. The standard main usally has 7-8 mineral tiles, and are usally arranged in a way to not waste space. MA makes a good example of a basic mineral layout

ADDITION:
[sub]And along with that, everything else seems very random. The bases are not the same size, the thin paths leading to the middle lets terran control the ground, the middle is useless, no one would want to take it for a 4 mineral expansion. If your going to keep it a ground map, and not an island map, the bases could really use a natural. All the bases have places you could drop tanks behind the mains and destroy them with ease.
Also, fix the problems you already know are wrong while your at it.[/sub]
