Thanks a bunch, balasa, rawwad, gough, DavidSmit!!
Balasa: yeah, I agree! For the final illustration I will prolly go for a stronger build for him again! 
David: thx for the thoughts! I completely agree with you - I think going for some traditional Samurai wouldn’t be that interesting, so I thought of something else now… 
What about a coffin that holds the darkness inside, unleashing it upon the foes in battle? 
Laurentiu also made a good remark about making the dark fog short-circuit the machines - I think that’s a cool idea! 
I should definitely settle on something soon, or I will not make it to a finish… O_O
Anyway, here are some sketches, definitely rather lame on a design standpoint.
I also really wanna have him have an additional weapon like a sword or a japanese bow beside the artifact weapon. I hope that’s along the rules… (?)
