First impressions, compositions is great. I like the tight crop. Focus is spot on where I think it needs to be. My attention immediately goes to your eyes. Which has a look of determination. I like the DOF which is making your chest blurry. I really like the fade to all black behind you. Job well done. The two things that I say would improve your photo is to try and avoid the hot spots on the sword and on your forehead. Really nice photo though.
This is a neat idea, but there's too much reflection in the blade, another hot spot on your nose, and way too much Neat Image. You look like you're made of wax.
Not a big fan of the inappropriate use of the Katana. As someone who studies Iaido, this is very disrespectful. I do like the photo on technical merits.
By the way you would never draw a sword in that manner. If you did, you could potentially cut your own neck or nose right off. Always turn the saya with your left hand so the blade draws towards the attacker not yourself.
