My opinion of this product is fairly average. While I believe the class is relatively balanced, the veils seem to lacks something and the essence cap in it's current form makes some of the veils abilities fluctuate.
First off you can't shape a veil that opposes your alignment (fine same with divine spells), then you find 4 evil veils, 0 chaos, 0 good and 0 law...
Second there is no interaction between the alignments:
-No way to get past aligned DR
-No ability to target certain alignments
-No down side to be neutral at higher levels (not a major concern, but high level effects for pathfinder tend to a little less forgiving against those who sit on the fence then "previous systems")
The scaling for the Vizier' veils essence cap is:
1-2 1
3-5 2
6-10 3
11 4
12-17 5
18 6
19+ 7
Given that a lot of the damage this class can deal is not based on a per day limit, it might surprise some GM's that over the course of 2 levels the damaged can potentially jump up 6d6 after lagging behind for a while.
There are no magic items.
There are no guides or rules to make your own veils, I'm only surprised because it was mentioned in a couple veil descriptions.
Since I have MoI I should be able to port over a couple aligned melds to fill this out a little more, but even then it is still a solid class.
I look forward to archetypes, and am glad the "smite feat" was left in the dust.
