Matt, that looks good. Thanks for posting.
I think larger spots of white shadow are not overdone mortal but shall be saltpeter. Low cost bricks get that white face after some time. It is very typical for sidewalls etc. Expensive bricks used at the front do not have that problem. I use it sometimes with that intension.
