Your cape also isn't enchanted, not a big deal but still an additional 200 agility.
Your haste is also sub 10%, haste should be 2nd priority on your stats after crit making your stat priority: Crit > Haste (to 10%) > Mastery > Haste (beyond 10%).
I've probably not picked up everything but it's a start at least!
