I love this style of video. The commentary is nice, and it's good to objectively analyze your own solves. The fact that you do this should make you loads better in no time.
Your cross definitely needs the most work. You're fast enough that you should be planning the whole cross within 15 seconds. You're only utilizing a fraction of your inspection time. Also, you're rotating the cube way too much during this step. A planned cross is more efficient in terms of number of moves, but it also is more efficient in how those moves are performed. I would start working on this by doing some dedicated cross practice. Don't worry about inspection time to begin with. Just plan an efficient cross, whether it takes a few seconds or a minute. Once you start seeing patterns and tricks, it'll get easier, and then start adding inspection time into the mix. I'm constantly finding new "tricks" for my cross.
Your turning style could also use some adjustments. If you watch, you'll notice that there are a lot of pauses followed by incredibly fast, jerky movements (like whenever you do a sexy move, or another common trigger). Try to make your turns steady and even. You are moving so fast and jerky during these portions of the solve that one of your hands is actually leaving the cube. While it seems fast, it's very inefficient, and ultimately you'll be able to achieve faster times with a fluid and steady movement that is more efficient. Additionally, turning in such a way hinders your ability to work on lookahead. It was at about your speed that I started really getting a grasp on lookahead. Try to emphasize smooth turning. Try not to follow your current F2L pair, your fingers already know what they're supposed to do, start trying to find your next pair.
Finally, try to cut down on unnecessary cube rotations. You seem to have a bit of a habit of rotating after every F2L pair. Don't rotate to find pieces. Get comfortable inserting pairs from all angles, only rotate if it's absolutely necessary to rotate to pair and insert efficiently. You should never have to rotate more than once per F2L pair.
Hope these tips help, and I look forward to seeing your progress. I'm sure it'll come quickly.
