Could be a track from the old School Ninja Gaiden if you think about badass ninjas. Or maybe even from the old Shinobi games. But alas, let's talk your track!
Simple, easy to listen, the only quips I have is that this isn't as improvised as you normally have your tracks. I can usually see some type of change up or something that doesn't make it feel too generic. I know you have that slow moment section and that weird standoff section, but it's kinda just there. Perhaps it's just me though but while this is another track for the books, it's nothing that I'd write the to the internets about.
Do like that it loops fine without much of a feeling like the track is reseting though. Not perfect, but you got things still going for you. Maybe just give it a bit more life in what's happening. Or perhaps as with most tracks that are original, give a bit of backstory. You mentioned a badass ninja but what's his story to motivate us to visualize this epic (possibly cyber from all the metal) ninja doing all this crazy shit.
