Are these c#5 good technique?

tm3916

I can hit (hit not sing) c#5 and c5s quite consistently now, there not the most musical sounding notes, but they dont feel too hard to hit, although with vibrato is hard to sustain for more than 3 seconds, my notes prior to the c5 (a4,bb4) are quite comfortable too, although i will say b4 is the note i struggle with the most at the moment, i overshoot and undershoot the note quite a bit, but once i find the placement i can do it fine.
I can also go up to a d5 with this voice, but find its inconsistent and i crack.

Also are these chest dominant or head dominant mix notes or pulled chest?
Appreciate all help.

Sounds like you are in a mostly chest voice, but they are strained. Its understandable when at the top of your range you struggle with notes. Find more space and relax your throat and use more support with less air. Be prepared for maybe 6 months or even much longer of constant training and readjusting to be able to use this note properly in a song. If its any consolation I can go up to a terrible A5 sometimes but any song with an A4 or above still gives me trouble.

@Wigs
ok that makes sense, thanks, I'll keep experimenting and practicing, I hope to make these notes useable one day.
