A dominant is a ruler, but never a tyrant.
Agreed

But to rule requires understanding, and understanding requires humility.
Somewhat Agree

A dominant has pride, but never arrogance.
Disagree, arrogance with foundation is fine.

But pride requires dignity, and dignity requires humility.
See point 2

A dominant commands respect, but never fear.
Disagree, I know plenty of subs who want fear inspired as part of their dynamic

But respect requires serenity, and serenity requires humility.
This is getting repetitive, see point 2 again

A dominant employs strength, but never force.
Disagree for the same reasons as my comments on fear

But strength requires knowledge, and knowledge requires humility.
...

A dominant criticises, but never derides.
Agree

But criticism requires insight, and insight requires humility.
100% agree

A dominant receives, but never takes.
Ok i'll buy this one

But receiving requires giving, and giving requires humility.
No, this is just factually wrong

A dominant completes, but never tries to alter.
Incorrect if both parties agree something needs to be altered

But to complete one must be able to see what is there, not what is missing, and this most of all requires humility.

Disagree for the same reason as above

I appreciate I am critiquing someone elses work, but figured I would as it was raised.
