Welcome to Heresy! As a footnote to getting more views on your list, there are army-specific forum pages (Space Marine Army Lists) for you to post on.
As for your list, have you given any thought to playing 10 man Tactical squads broken into combat squads, leaving your heavy weapon selection backfield and bringing an assault weapon to the front? Your heavy weapons inside a transport with no firing point are pretty useless until the turn after you disembark (snap shots as you move to get out), putting assault weapons inside the vehicles mean they're firing at full capacity upon exiting. Plus leaving your heavy weapons backfield will help capitalize on your range since chasing Crisis suits is a fool's errand. It would mean you have two less tanks in your army, but those points add up pretty fast.
