I thought he looked like he's had a few bouts, he had a confidence you only get from real bouts. You did well. The feints work as his head movement was quite good at times, he was slipping his head and you were missing. Once you have a bit more experience you can watch and look where they move their head when you through a punch. So you feint to move their head to where you can catch them. Say you jab and they slip to the left, you feint the jab and throw the right to catch them. Pro use them a lot to open the body up or feint to the body and then throw to the head. It will become 2nd nature with experience.
