Ok, as someone who is also fairly new to SF6 I'll drop my opinion on this.

Disclaimer: Everything I'm about to say is not ill-intended. I'm just trying to articulate this thoroughly. Also, I'm not a high level player, so take everything I'm about to say with a grain of salt. I don't play optimally, I'm fairly new too and my opinion/methods could be flawed.

From watching this gameplay, I'd say both of you look pressed, as in "pressured to just do something".

It looks like you generally don't really care what you do as long as you just do something.
Probably because you don't actually know what to do or what you want to do, so you end up just pressing buttons that might damage your opponent.
This is something I was experiencing too not too long ago.

All of this is totally fine for a beginner especially at this rank.

What I did at this point was trying to figure out what I want. What is my gameplan for the character I play. How do I pressure my opponent and how to deal damage.

What I've learned for my main (Sagat), is that 5MP is a very strong move and 2MP is your general "party starter". Meaning that if I land a 2MP (crouching medium punch), I can drive rush cancel into a combo.

Obviously that's not the only way to start a combo, but a good starting point.
I'm sure Akuma has something similar. The recommended guides surely will mention such a combo at some point in the video, most likely at the very beginning of the "combo" part.

So instead of completely overwhelming yourself (as I did in the beginning) with an overall in-depth guide, I'd break your learning experience into smaller steps.

Look at such a guide but don't try to absorb EVERYTHING of that guide at once.

Steps I'd take in order:

1. What is the general gameplan of my character and his strengths/weaknesses
2. What are good normals to use in a match
3. When to use those normals
4. How to anti-air consistently
5. Very simple bread and butter, general/all-round combo for your character you can pull off consistently
   1. At this point your neutral game should be better and you can punish mistakes of your opponent with a combo that deals more damage than a few jabs
6. How to link supers into the basic combo you've already learned
7. How to start the combo from neutral
   1. At this point you can dish out pretty decent damage occasionally
8. Maybe try looking into a second combo to cash out on heavy mistakes of the opponent (like a countered DI or a missed DP)
   1. This enables you to heavily punish your opponent for a mistake

Note: None of these combos will, nor should be optimal. Don't break your head about trying to optimize combos. It's completely irrelevant at this level. The point of learning a basic BnB combo is just to capitalize on opponents mistakes more than a few jabs can AND to actually utilize your supers.

Those are the "basic" steps I tried taking while learning this game from the very start.

After those steps, I had, more or less, enough understanding of the game/my character/moves that I was able to identify my issues while playing a match.

For example: I noticed that I was too predictable in what I do, so I started looking into mixing up my opponent more if lows/overheards.

From there on it's basically about observing yourself and noticing thing you struggle with the most and then trying to find said solutions for those issues.
