This is a good Tzeentchian based list. Winds may be an unexpected win for you.
I'd say CC lists, IG Vendetta lists (or blob), and MC heavy lists could hurt you.
That beiing said I'd consider the S8 psyker power (Bolt of Change? Don't have my codex on me) for more range. Winds does give you a better chance to glance and good chances to wound high Toughness creatures but you're lacking range. Just a thought.
