That is a nice list!
However, Biovores are also a very awesome addition. Taking Regen off of the Flyrant and Crone, then dropping the 4 Warrior squad down to 3 would allow you to take 2 Biovores, and then have 15 points left over, which would allow you to give a set of Boneswords to the Tyranid Prime. He is a monster in close combat, so those would be a nice addition. Take the Deathspitter off of the Tyranid Prime though, and give one of the Warriors a Barbed Strangler. Replace the Devourer on the Tyranid Prime with Scything Talons as well. That will give him 5 attacks at AP3 in close combat.
So summing up everything, this is what the list would look like
Flyrant with 2 twin linked Devours with brain leaches
Tyranid Prime w/ Boneswords and Scything Talons
3 Warriors with 3 deathspitters
3 Warriors with 2 deathspitters 1 with Barbed Strangler
1 Hive Crone
1 Tryogon Prime w/ Toxin Sacs.
So with this, you have your Tyranid Prime joining the squad of Warriors without the Barbed Strangler. You don't want to put them together because this will force your opponent to choose what he wants to fire at. Does he shoot at the squad with the Prime, or the squad with the Barbed Strangler that is pinning his troops? Keep the Venomthropes behind each squad of Warriors, then put a squad of gaunts in front of the Warriors, the gaunts have a 5+ cover and Warriors have a 3+ cover. That will allow you to move up the table with some safety.
For psychic powers on the Flyrant, if you get The Horror, keep it! You can use The Horror to try and pin one of your opponents shooting squads. You can then shoot your Biovores at another two squads, and the Barbed Strangler at yet another. If everything goes well, you can pin four of your opponents shooting squads and increase the odds of your army making it up the field. Pinning tests are your friend.
One thing to think about when deploying your army, do not worry about deploying your Zoans with the Venomthropes. The 3++ save on the Zoan is just as good as anything the Venomthrope can give you, so don't limit your deployments by scrunching everything around the Venomthropes.
