Man that stuff is looking good! Great job for your first stick burner run!

You could try a fire brick. Lay it across the firebox hole from the inside, it will restrict some air flow but it will retain heat. Adding a water tray like Smitty suggested with it will also aid in temp control and moisture. Damn fine cook though, congrats.
