Okay bro i like what you are doing, but i feel there are things in this situation can be worked on. 1. Please Keep it a habit to have your hands up to your chin or higher. Personally when im trying to improve a defensive skill, sparring is the best in my opinion but i think its better to learn things one at a time. Such as you first learn how to parry, then to catch shots on your block, then you put those together, and then you can start bringing other stuff. 2.When you throw a punch, you must throw with the intent to hit. If i dont have intent im just wasting energy because it will be likely i will miss and offer an opening to my body or head. If your throwing a double jab, you want your second jab to be where your fist or elbow would be behind or next to their face. (To guarantee it lands and it gets you in the pocket.) 3.I would recommend getting used to getting in and out of the pocket instead of staying in the pocket. im a shorter fighter. at some point, there's going to be a fighter who knows how to use range and create space. if you cant cut off the ring, i would prefer going inside and out of range. Throw 1-3 shots then back off and re-enter. 4.Also just another tip, it helped me well. Get used to moving left and right laterally, change it up. At some point it gets predictable and feels easy to take advantage off. Change the Rhythm. I Drilled on the Bag, in spar, and shadowboxed myself getting used to synchronising my feet with my hand and feeling comfortable to punch going left and right. i Usually prefer to stay in my orthodox stance. If you got something you disagree with, have trouble understanding or smt else, dont be afraid to ask either. This is all of my opinion, advice and it could differ to what other people say, my best advice is if you have a coach dont be afraid to ask them.
