Your writing has a great flow and rhythm to it. I think you've got a great start and lots of talent. It's important to balance narration and description and inner thought and various elements, as well as the rhythm between long and short sentences or fragments etc. There is a very precise and careful art with it. You do that with confidence. In my personal opinion, your writing has enough poise, sophistication and eloquence to aim for the more "literary" which means to say, be careful with how dramatic or exaggerrated it gets. Right now like saying the weapon passed through him, is perfect. It's a fantastic way to go about it, not giving too much information but still having enough for the reader to understand it. Simplicity is good in certain places to refrain from being stereotypically overwritten when it comes to action scenes or over-narration, while other seemingly less dramatic moments can be more elaborate - since it's less expected and more thought-provoking etc. But anyway that's a great start. I would just say keep up this rhythm, don't get too dramatic or exaggerrated. Especailly for battle scenes, if you were actually in such a position, regardless of a trained soldier or samurai, there would be a sense of hollow detachment, a haunting devoid of certain sensory experiences, because of the danger, the adrenaline, being in the moment and reacting on instinct. The human brain cannot process much unnecssary information in the heat of the moment - i.e. some writers going on and on about every visual detail of each sword stroke (unrealistic). You don't do this, so that's good. Cool stuff.
