Am i Doing it right??

Hey there friends,
I have been doing volume 1 for about a month consistently now and i just wanted some pros to check if i have the AH excerises down correctly.
There are 2 examples in this video, the first is me opening the throat more as i go higher, the next is me trying to keep that bright sound, but the throat isn't as open.
Which one is the correct way to do it?

This video is me going through the AH Excerise. Is it okay?

Your second video has you almost sirening through the scales. Try to "land" on each note individually more. I know that can seem hard at first, but you will learn it if you concentrate on it. In the places where you are speed-bumping, you should lower your air pressure a bit.
Your range sounds good. Your tone is good. Land on those notes.
Good job.

In order to get that bright tone i closed my mouth almost to the point were it is totally closed.
Then i experimented with my voice, what it felt and sounded like when it was really bright.
Then i put that feeling and sound with open throat and open mouth. It felt more easy this way.
I dont know if this is a good tip or not but it works for me.
