It looks just a bit overmilled, but not too bad. The hulls should really look more cracked than completely separated from the interior grain.
I think this type of milling would be fine if you have a good false bottom or bazooka screen or something like that. The size of the interior grain looks big enough that it wouldn't cause stuck sparges.
Worst case scenerio, a bag of rice hulls costs $1.29 at my LHBS. Wouldn't hurt to add a bag to your mash.
