Zach, speaking from only doing a couple backyard type competitions and a have yet to receive my CBJ card in the mail, but you may get that trimmed look on your brisket slices better if you square up the flat of the brisket while trimming. Find the grain and square up the flat to a little bigger than actual turn-in size (accounting for shrinkage). That way you get the more square look and a nice bark all the way around the slice.
Ill agree that i think everything looks a LITTLE wet, but all in all id love to judge those boxes.
