This is fantastic!!!

amazing

the art work is spectacular, and the scene it depicts is incredible.
the setting, so serine, a delicate field under a blooming cherry blossom tree.
the subject, in stark jeux d'opposition to the setting; a fierce samurai warrior, suited for war, brandishing his steel.
and yet, in his eyes, and this is the most impressive bit, he looks so weary, so tired. he has done this a thousand times before and can not imagine how many times he will do it again, and he is so beleaguered by...what? perhaps memories of past conflicts? or maybe just the slow unrelenting grind of time.
I love it, in case you can't tell.

Too epic! But you could work a little on the reflection in the sword, make it a little more refined.
