Only things that stood out to me:
Chicken: Could be the pic but looks like it needs some color. If I took a raw thigh and dipped it in the sauce it wouldn't look much different. Maybe some grill marks or something.
Ribs look great. Maybe a thicker bed of greens?
Pork: Possibly have some separation between the different cuts? Not a lot but enough to distinguish the pulled from the chunked from the sliced.
Brisket: Perhaps line the burnt ends up and fan the slices a little more.
I like all of these boxes. The stuff I mentioned is very minor.
