Just started playing 1500 pt. list

[nuckifyabuck]

First off, just want to say hello to everyone. Figured I would start playing (got a few of my buddies here in Afghanistan that are all starting to play as well) and have a good idea on how I want to play Tyranids. I've always thought of tyranids as a pure swarming army and decided to go with that approach. Here is the list I want to run, 1500 points. Was going to see what kind of tweaks I could do to it.

HQ

Hive Tyrant
Adrenal Glands
Hive Commander
Stranglethorn Cannon
Psychic Scream
Scything Talons
The Horror
Tyrant Guard (x3)
Lash Whips

TROOPS

Hormagaunt Brood (x20)
Adrenal Glands
Toxin Sacs
Hormagaunt Brood (x20)
Adrenal Glands
Toxin Sacs
Termagant Brood (x20)
Fleshborer
Termagant Brood (x20)
Fleshborer
Tervigon
Adrenal Glands
Catalyst
Toxin Sacs

FAST ATTACK
Gargoyle Brood (x10)
Adrenal Glands
Toxin Sacs
Gargoyle Brood (x10)
Adrenal Glands
Toxin Sacs
Gargoyle Brood (x10)
Adrenal Glands
Toxin Sacs

HEAVY SUPPORT
Biovore (x1)

This is my first army list so I know there are probably tons of things I can do to make this list better. My whole philosophy is tons and tons of fast troops, using gargoyles as distraction, and then overwhelming with the Horms and Terms. Anyways, thanks for the help and criticism ahead of time.

I would take off adrenal glands, The Horror Stranglethron Cannon off the hive tyrant. Put toxin sacs so you wound on 2s and reroll 1 to wound, put heavy venom cannon on if you want a blast weapon but its better to have the whip and sword. Forgot the name of the power but get the one that lowers enemy units to WS1 BS1. Take the glands off the Gargoyle's if your going to use them to draw fire they dont need to cost that mush and the glands just make them that mush more costly to filled. You can also take off the glands on your hormy's they dont realy need it but its alright to have. If you still need to fill in points get some other modles that can help out your list. Like onther MC to draw fire a good one would be the trygon
