Looks alright, just a couple of suggestions -
The HB's on the Valkyries...seen as you'll need to move slower to shoot them they aren't always that effective or worth the points spent on them. They are actually better on the Vendettas for that reason.
Spending 4x the points for a HF over a standard Flamer isn't worth it in most instances.
Astropaths in the list would give you access to a more diverse range of Tactics for the Valks/Vendi's...choosing the Board edge etc.
I won't bring up the subject of using Vets over ST's...I find that to be a personal preference issue.
Best of luck with it...Air Cav do look sweet on the board.
