There are several near identicle colours on this piece. With some slight repixeling, I have it down to 30 colours with relatively no quality loss at all.

love the use of black (larger canvas) and love the retro-ninja-gaiden feeling it inspired!

A description (back story, ideas, etc) would be nice!

I'd add some stylish gradient to the bloody background then place it on T-Shirt and wear.

Awesome! I am loving this!

i like it very much, gives a samurai feeling instantly!

Amazing! The canvas makes it seem like a comic book page. I really love it!

 looking great! almost filmic.

I really enjoy the use of black here. Adds a lot to the atmosphere.

Shoe, yes they can.

I enjoy the canvas, nice work!

The canvas seems a bit too big. But otherwise nice.

Holy shit, this is cool.

But umm.. 39 colors?
