[@karamonnom] Unarmored Movement would benefit your Fly speed too! It does not specify Walk speed! The exception is something that sets a static speed stat such as the Fly spell, but since your fly speed is innate it also gets boosted! Enjoy a fly speed of 50 that will just keep getting faster!

Please specify your kensei weapons for me. :) 

The Fading of the Old Nimbus racial flaw is one less HP [i]per level[/i], so you’d have [s]two less hit points[/s] one more hit point, assuming you took average. +1 con/-1 Flaw; 8+5+5 = 18 from class hit dice with your net +0.

Otherwise seems good to me.
