Good work. Try to get a rematch with him if you can. Since he won the tourney he must be pretty good and a good milestone for your development if you can beat him in a rematch. Revenge is also never a bad thing.
Could you make 165? His power really seemed to throw you off. At 165 your size advantage would be a huge help to you and you'd be the powerpuncher in most situations. Aside from that, footwork. As some folks pointed out, your legs are way too far apart. It probably helps your power some, but if you don't land it doesn't matter. You tend to come in hard and sometimes land nicely, but you're stuck once you're there. Try keeping your base under you and not leaning in when you throw the left. Jump in to land and bounce right back out. Then go back in if you have them rocked. Most of your issues came when you committed and then couldn't defend yourself or escape quick enough.
Thanks a lot man. Yes, I think I can make 165. I am a 178 without dieting and eating like ****, so I believe that I can in fact make it. It's just going to take some extra dedication on my end. Also, thank you very much on the tips.
