Looks great! As you shoot for 225, don't freak out when you don't hit it exactly. Smoking is an art, not a science, and is really pretty forgiving. So if it's 200 some times, 250 others, and even 300 others, don't sweat it. Temp adjustments with the bottom vent take a little while. You could drive yourself crazy "chasing temperature."
Have fun, and give us some after pics!
