seems a decent enough shooty list to me, but you have nothing for melee, against some armies you will benefit from a few cc items (I like the venomblades as cheap upgrades, really helps with the MC's)
Archon could do with some sort of save or a str6 will ID him.
Quite a small amount of anti-tank too, if you play vs mech'd armies I would use lances on the raiders instead of dissies, you have enough poison to hit troops
