NICE! I love how instead of Zangetsu's all black (hair, beard, clothes) it looks like you combined Hichigo/Shirosaki/HollowIchigo with Zangetsu (the artistically messy locks). This looks even better than Kubo's version, I think.
I'm not a big fan of Bleach, and lost track of the story long ago... but darn, I can't help but loving this drawing and the warmth it has despite all its cold whiteness. I really like their interaction and expressions, and I also find your colouring, simple as it might be, truly lovely. How nice! <333
The cuteness! I like how you did their eyes, like they have depth to them. You really could say something poetic like, "pools of amber", cause that's what Ichigo's eyes look like... I'm starting to lose my coherency, aren't I?
