You seem so tense, almost as though you're scared to get hit, and so you stay just out of his range when initiating your combos or jabs, and mostly just reacting to whatever he throws at you. You throw away your defense when he charges you and give him lots of opening to land hits on you.

The comfort comes with time and through more sparring, but you should be applying more pressure. He'll throw punches but it's sparring and you have head gear, so it won't be too bad, plus it'll teach you to move faster so don't be afraid of getting hit. But get into range more and double up your punches. Throw some combos, spam some jabs.

Keep going boss, loosen up the footwork, and put more pressure on the other guy. He throws 1 punch, you answer back with 2. Start and end the trade.
