the only glaring problem i see is the flamers, get rid of them. they are useless for the guard, take plasma rifles instead. take lascannons or heavy bolters if you can, they shred really well. also, one of your squads only has 5 or 6 gurad in it, the minimum size is 10, take them out, or expand. other than that its legal for what i can tell. hope this helps, good luck!
