Nice job - but I agree with James about the repetition on the brickwork.
I have found that textures showing only horisontal joints work better at that distance.

You can retain the original texture for closer views.
Eric,
the trick is to know that not every project is a candidate for a sketchy style.
The moment I feel the slightest doubt, I quit styling.
This one felt right for the job, from the very beginning.
