Looks really good.  Great cook to top off a great restore of an old WSM.  One bit of advice - if you care about your concrete, put a pan or something under the WSM.  At times it will drip something that runs out the vents and down the charcoal bowl.  It's a brown liquid so I assume it's condensation running down the inside and out a vent and mixing with smoke or gunk from the inside of the cooker.  Anyway, I'm sure it will stain your concrete if you let it.
Again - congratulations on the WSM and your first cook!
