Combined Arms Comp List

I'm trying to get more into comp lists for combined arms and this is what I came up with, hoping to run it at a tournament, any input would be greatly appreciated:

Gaunt's Ghosts

Ursula Creed

2 RDTCs: Oppressor, Pulverisor, MMs and Stubbers

1 Cadian Command Squad: Plasmas

1 Cadian Squad: Melta and Plasma

2 Catachan Squads

1 20 man Krieg Squad: Melta and Plasma

2 Kasrkin Squads

1 Hellhound

2 LR Vanquishers: MMs and Las

2 Tauroxes

1 Chimera: Flamers

Gameplan

Kasrkin go in Tauroxes and Catachans go in Chimera. Kasrkin for early game moveblocking, Catachans for trading and secondaries. Vanqs for objective holding, moveblocking and possibly trying to fight vehicles. RDTCs for the bulk of damage. Ursula with Cadians and and Cmd Squad to hold home and give out orders. Hellhound for support and overwatch threat. Gaunt's Ghosts to do secondaries.

This list is likely to face a variety of meta lists, so probably knights.

Looking for feeback and how best to run the list.
