I'm with Sharla, looks like you want to be in the ring!

If that guy has been boxing for 7 years then pretty soon you're going to be able to say you're better than some one who's been boxing 7 years as long as you stick in, practice and think!

biggest mistakes I could see is that you only ever moved one way and you kept putting your head down, big no no! it's good to see you trying to roll shots, but remember: the knees, feet and shoulders move, not the head/spine.
