Not bad, a few things though.
I'd drop the melta bombs on the aspiring nurgle champs. Not too useful when he is running alongside 2 melta guns and is carrying a power fist.
OR drop the melta guns and grab some plasma. Plague Marines are easily the best plasma gun troops in the game now that they have FNP.
I'm not a fan of the noise marines, seem points heavy for what they will achieve, I say drop them and dump in more raptors or buy some havocs with a bit of AT firepower.
I know it's tempting to roll the Twin lightning claws on the raptor champ, but a power fist is better (I think he can take one).
I'd find points to run the lord with a jump pack (accompanying the raptors). right now he is going to be left behind babysitting the deathguard (who don't need a babysitter, they are old enough to be left alone
). If you can't find the points elsewhere I'd downgrade his weapon. You can still use the model to represent a power weapon etc.
