I'd give you 4s or 5s across the board. Those are some rough boxes but you have to start somewhere!
Chicken looks underdone and a bit like you fumbled them with your tongs pulling at the skins. remember to try and handle the chicken from the side or underside to keep from marring the top. Brush some sauce on them or something to get the color consistent. Trim them down a bit as well.
Ribs look charred and like you cut them with a sharpened spoon. Practicing cutting ribs after cooking. Consider an electric knife. Again, some sauce will go a long way to not making meat look dry as a bone.
You're brisket looks just like our first box! Burnt, dry, brown splotches on the meat, unevenly cut...hideous in short! Take heart, we took 3rd out of 50 last time...you can do it! If you aren't going to sauce it, spray it with some juice and a touch of oil after. Really pick where you want your turn in to come from and then first trim that area up and then cut the slices from it. Electric knife can help. If the burnt ends look...burnt, then don't turn them in, just put the best you have in the box. Our burnt ends got destroyed last time out, and again, we did pretty well, but knew to leave them OUT of the box.
