Such great style you have there man! Especially at sits, where I find those combos really flowing and effortless. Nicely done!
However, at lowers, not always, but sometimes you are still breaking some combos. Try not to do that man because your lower style actually looks good, keep on improving on the breaking combo thing and you'll get even better.
And it appears you don't practice uppers much do you, lol

! It's good though, just do what you like 1st. Other things later is ok.
