Props for putting your video up.
So, here's my critique:
1. You seem light on your feet, and you seem like you move really easily. That's really good. I would try to keep that.
2. You've got a pretty nice side kick, there. Now, he mostly got out of the way of it, but that doesn't mean it doesn't have value. You might just not be throwing it at the right times, not setting it up, or telegraphing sometimes...something like that.
3. You're flexible and quick enough to throw a variety of kicks at every height. I saw some hook kicks, some roundhouses, some teeps...great.
now, the flip side:
4. Not so much with the combinations. You look like you want to throw multiple punches, but like you're having trouble getting them off.
5. Punches in general. Not as strong as your kicks.
6. Defense. Even worse than the punches. (Not trying to be a jerk, but that's what I saw.)
7. Not a lot in the way of lateral movement.
8. Control of distance. Even though you've got good mobility, you were hardly ever in the lead. He wasn't consistently in the lead, either, but we're talking about you. If he asks, we'll talk about him later.
You've got to do a better job of controlling the pace and distance of the engagement. With your abilities, you should be able to decide when the two of you are going to engage, and when you're not. But, in order to do that, you're going to have to move in and out more decisively, and you're also going to have to make your defensive movement better. By better, I mean you're going to have to learn to pivot away from his attack, sidestep or even (gasp) slip and duck his strikes, rather than back straight up, or lean your head back.
Now maybe you felt like you had to engage at some times that weren't always the best. It kind of looked like he waited for you to throw something so he could counter, especially toward the end. Maybe this was just practice and you didn't want to wait--or maybe you just need work creating offense.
And about that--creating offense, I mean--don't wade in slowly while leaning your head back because you're afraid you're about to get hit. That's a rookie mistake. If you're gonna get hit if you throw that punch, don't throw that punch. You go in fast, with your head tucked close to your shoulder, and you're faster, less likely to get hit, and you get hurt less even if you do. If the opening's there, or if your first punch can CREATE the opening...BOOMBOOMBOOM--you fire off the combination without hesitation. YOU fill up the space. If you work at it, the act of throwing a punch will even cause your head to move sideways into a better defensive position, anyway. You've probably got to do some slower drills to get used to slipping or moving your head off the line of his attack as you attack. And maybe even try to force yourself to slip or duck some punches in light sparring. Plus, it's easier to go in confidently when you've created an opening for yourself with a feint, or stepping quickly to the side, then attacking while he adjusts. And, you don't always even have to be moving forward to create offense. If you can react well enough to what he's doing, an opponent is always most vulnerable when HE's throwing a strike. And, you can anticipate or bait him to throw the kind of strike you know you have a good reaction to.
One last thing: when you do decide to go in, you don't have to JUMP in. In striking arts, smaller steps are generally better than taking big steps. And keeping your feet closer to the ground when you move is better than jumping or lifting them way up (unless you're checking or kicking with that leg, obviously). You can start your attack from JUST outside of his range, and then take a little step in, and then back out. Or better yet pivot out. Or even step out not in the same direction you came, or even end on a kick or push him and then kick him again... whatever.
Good luck and post again when you've had a chance to try what you wanted.
