Very good!
I use a similar set up and it works fine,
it's hard to tell from the video but one possible change would be to use a static line for the microtrax line . I just do it as I feel a static line would be more likely handle a fall on the micro's sharp teeth .
To position the microtaction higher i use a short sports quick draw with two lockers to give it a bit of height , then an old head touch head band around my neck which is connected to the micro in a similar way to yours . I did it this way as its stretchy and I can whip it off really quickly if needs be .
It's also worth mentioning that having some prusik loops , slings and a knife may come in handy in the event some thing get's jammed and you have to un-weight a rope . Now this is unlikely in straight forward climb were you can probably always get a foot hold but if you ended up hanging in free space it might be important .
Nice work ! people are always asking how to do this , and this is a clear video .
