First off, let me just say (and Mods, I know this is not totally kosher) but, pics would be a real big help. I have had brisket that once done has a smoke ring that was a little on the gray side, but, I could see the distinct pink ring at the edge of the ring. I am not sure why this occurs, but, it does not mean it is a bad brisket.

I seems like you rested it long enough to make sure the meat was properly rested, however, did you wrap it in foil and place it in a pre-heated cooler or other container? I find that resting in a pre-heated cooler makes for a better end product.

If it tasted good and was tender, sounds like you got it down. Smoke another one soon and see how it comes out. And then some more.
