Don't try to teach yourself how to box, you definitely need a trainer or at least some help from someone who knows a little bit about the sport. It'd be like trying to learn how to play guitar by yourself without going off of anything, you might get there eventually but it would take forever for you to be decent.
umm, ok, I didn't watch the whole thing, but a few pointers based on your general tendencies. -it's ok to move your left hand around a little, but you have to keep your hands up -you seem afraid to get hit...you would sway backwards or block but kind of turn away....you gotta just get in there and scrap -work on smoother footwork...i.e. don't cross your feet and don't walk around -more head movement you seem decent, so I'm looking forward to seeing more videos as you get more experienced
..........not a whole lot of good about it I'm sorry to say. You dropped your hands way too much, you were wide open for a left hook. You need to work on going to the side more Try to slip more punches instead of turning away Don't back hand. You did it at 0:22. Work on punching technique NEVER put your hands out to the side and put your face down, thats how you can KO'd. You telegraphed every punch. Honestly, I don't know how you landed at all. Ok, thats all for now, I will probably find more later.
You're game sucks. That's it. I'm sorry but after 8 months of training in boxing this is shameful. You need a professional trainer or a skillfull boxer to teach you everything from scratch.
