Guard is definately tighter
During the first half of the round your range was out on your hooks- you were hitting shallow, not in the 'belly' of the bag so causing a push effect, spinning it like a top. You self corrected your range however, and the hooks took on a much more powerful role later on.
You have a snappy jab when you lead with it, but have a tendency to lose that snap when you lead with the right in a combo, thats not a huge issue, but maybe thinking more about the next 'proper' punch than the one you are throwing?
your best work comes in the last 45 seconds, a strong finish is a sure sign of good pacing, and your speed combos are very impressive, its easy for us bigger guys to lose a bit of balance from punch 3 onwards, but you keep tight form throughout.
Once again, you are looking like a very handy boxer
