My first ever brisket and cooked it on a smoker made in the backyard

First ever time cooking a brisket was pretty happy with how it turned out, was definitely a worthwhile labour of love cant wait to do it again now.

Smoker however, will definitely need some improvements before the next usage temperature was a little impossible to control well but worked out in the end.

Any suggestions on the brisket or the smoker would be very welcome.
