Very nice illustration. I particularaly like the také forest in the background.
A (very) small comment on the sword hand though. At least in the school of japanese swordsmanship where I practice we always hold about one finger breadth down from the tsuba (guard) to have good freedom of movement. If you hold all the way up to the tsuba you might scratch yourself on the steel. Though if a correct grip will look good in a picture I'm not sure.
Great picture, very good. He's got a whole lot of blades there - a katana in his right hand and probably a wakizashi at his right shoulder, with the shorter hilt. What about the other two? I'm rather curious.
