Sorry if the feedback is long
I can see the difference between the previous project and this one after the tease but the problem remains more or less the same I find. It's complex and fast
Here are my few suggestions:
- Spoiler: show
- 1) I will suggest to indicate the patern when it changes (example 5 - 3 - 2 then 1-1 according to the trailer but it changes very often and I think it could be annoying to edit).
2) Personally, I suggest following the tempo of the drums and not the vocals, it's easier to follow the rhythm without the music being distracting. (especially with this style of music which is sometimes unpredictable)
3) Otherwise as a little trick to help yourself, I suggest to tap the thigh with your hand and try to reproduce the paternal to see if it is possible to follow the rhythm correctly, so that we know if it is too much quick or complex for the hand or if it makes the hand tire too quickly.
4) Another suggestion would be to add a little pattern noise like in the webtease so we hear the real beat meter rhythm (I don't remember what we call it but it's like the sounds of the metronome for example)
In short, I am not saying all that to be mean or to judge all the negatives, I saw your other CH on xvideos, you have a lot of talent to find the good videos and to be creative, I know you said you don't usually play CH bit I know that you have potential but every time I tried it was hard to follow ^^.
There is a quote from Winston Churchill which says:
"Success consists of going from failure to failure without loss of enthusiasm".
In short, we learn from our mistakes, keep your heads high!
Anyway, I can't wait for the next project to come out!
edit: edit: Uh, I just saw you did a beta test in another topic so
you can forget everything I said lol 
(
except maybe # 2 to follow the rhythm of the kick of the drums when you hear it, this is what gives the rhythm in a music). It's much better in the beta!

And like the others said in the other topic, I think it's better if the beat meter was down instead of next to it, but it's not bad vertically either, I just think everyone is more used horizontally at the bottom.
The only real comment I have to say is that your 3-3 looks more like a doubletime since we don't seem to have a break between each one (and I imagine that if we visualize the drummer, it was probably hitting non stop instead of 3-3. And if it's really the 1st round, looks like i won't last long ^^
