Oh Lawd! All aboard - for my Night Train! Heh! What did your Night train brisket look like when it was done.
I see you are using the Night Train spice technique on the smoker. However, of course the Night Train gets cooked in the oven. Now on this cook, the meat looks spectacular! Salt and pepper and mastering duplication of the Night Train on the smoker as a next step can place you miles ahead of the typical novice. Maybe even some veterans.
Whether you use foil however is more dependent on your pit temp. Lower temps that are more toward the 225 ranges then sure, if you want the more traditional temps like a pit temp of around 280 0r above (this is the temps of our true forefathers in Beef Que - sans simmering) then less foiling is needed until resting.
