I watched 30 seconds. You've got the up down hands. That's fine against hard to time fighters (mainly due to speed) so you can't anticipate or read their shots. The problem is it is defence then offence. Either pick off your opponents shots i.e. if he jabs, you catch; rather than hands constantly going up in hope that it blocks anything coming your way. Alternatively, try to blend the two (offence and defence) i.e. as you jab, your hands open to catch his jab.
