Others have answered this very thoroughly and much better than I could. But I do have one piece of advice for you. Learn to fight like Hamza. I don't know your training background, but after a certain point, you'll see what your preferences are and as time goes by, you'll develop your own 'style.' I don't mean that you'll create a new system, though who knows? Perhaps you will, but what I mean is that you will make what you practice your own and what you do will be yours, not you fighting like someone else.This is going to be true no matter what you practice, be it Wing Chun, JKD, Muay Thai, or anything else. I wish you the best in your training!
