I think it looks pretty good. You have plenty of fire support and anti-tank. And the Autocannons can take out both light armour and infantry, so they really count as a bit of both. Same with the missile launchers. Your Storm Troopers have mobility with Deep Strike, but I might bump them up to at least 8-man squads, 10 if you can. They're good but they're not Space Marines... and I feel vulnerable putting even Space Marines in 5-man squads.

You can take the Carapace Armour off the sergeant to free up some points as with majority armour saves, it won't be too effective. I might also remove the sniper squad, or make the Hardened Veterans into a sniper squad to free up enough points to get the STs to 8-man squads.

I'm not really a Guard player, so that's about all I can give. One other thing I might suggest is perhaps getting rid of a Heavy Weapons platoon or two and put in some armour.

But if this list has worked well, then unless you find something really glaringly wrong with it, don't change it!
