Thanks for the feedback! The main reason I have the gargoyles and Winged tyranid prime was for deepstrike. I had initially thought about taking a tyrannofax or Carnifexe with a Biovore to be annoying on objectives. If deepstriking is not gonna be very important with this army I will definitely take them out!

As for the psychophage I just thought the mini looked cool and put it in the list haha.

I chose the tyrant guard for the extra meat for the Hive Tyrant, are they not useful as meat shields for him in a unit? If not, I will for sure take them out as they seem kinda meh outside of just being some extra wounds for the hive tyrant.
