Ok, here is a video.
Could you tell me my faults.
This is not full speed at all its just a demonstration.
I am just going to type this as I watch.
Ok, right off the bat, your centers are inefficient (i assume you are doing white/yellow in beginning, did not check/verify if this was correct, I only paid attention to those). I have no idea why you are doing them like that. What I do, is pair up a line (2 center pieces) and then, assuming theres no center pieces already in place, just Rw U2 Rw' (basically just put the centers up there) and then just make another 2centers line and just insert them into the center. Its so much faster then what you are doing. This is up to when you are finished with yellow/white
Ok, I am going to assume this is yau. You are not doing yau though. These are the steps
opposite centers
3 cross pieces in place
finish centers
finish last cross piece
3-2-3 edge pair
3x3 stage
you seem to be finishing all the centers before cross pieces. let me watch more (31 seconds into it, had to pause to point this out)
As you can see, because you finished centers already, you are terribly restricted into what moves you can do when creating the cross pieces. The first 3 cross pieces (for me at least) is by far my slowest point in my solve, and you are simply adding time in the solve by restricting yourself. Also, do you normally pair on M slice? I find lookahead much easier if you do it on the E slice, very strange. If you are used to M slice pairing, then ignore this, it just seems to hinder you a bit because you did not rotate to do the cross pairs, and you have to worry about messing up your centers. Just a little note.
There are too many mistakes in this. I am going to make a video of me solving. My way is basically the way sebastian weyer does it, as I learned from his videos (I think?, cant remember, but pretty sure). You can adapt it to your own style. I stopped at 1:21 in. I am sorry
I will PM you when I am done with the video. I am unsure If I will finish it tonight, as I have to wake up early, depends on how fast I eat my dinner
