OK, this is what I see. Watched it four times. Remember, I'm not an expert on anything, and this is generic observation stuff, might not apply to your style.
1) Distance. You're both too far away.
2) Gold belt needs to keep his elbows in.
3) Don't just block with your gloves. Drop arms, block with elbows, deflect, get offline. You don't have to receive every punch or even deal with it if you can avoid it.
4) Jabs are nice but not powerful. Use them to set up the next shot. I see the guy without the helmet did that pretty well. Gold belt not so much.
5) No-Helmet throws half-punches to connect with Gold belt's head or body. They connect, but they're not real punches. More for show than go.
6) Several times, No-Helmet leads with his face and lets Gold belt inside, but Goldie doesn't take advantage. Real fight, someone will remove that noggin.
7) Bouncy feet. Maybe good for TKD style kicking, not sure if it's that great for stand-up punching. If it were me, I'd try to time those hops and attack while the opponent was in mid-air. Might work, might not, but I'd push in every time those feet left the floor.
