Previous advice comes fom those more learned than myself. I have boxed amateur for 8 years but that was 100 years or so ago. I think your hand speed is fairly impressive. Your stance is too wide as mentioned and I believe if this can be corrected you will notice a difference. The people on here genreally know what they are talking about and if anyone named grey, andre or scrap say someting thing then it may be worth listening to. If you were hopeless you would have had no response other than sarcatic remarks. (Others have good advice as well. They just came to mind.) My big thing was speed but you look faster than I was and I did fairly well, so best of luck to you.
