This is one of Mirror's attacks, Glass Manipulation.Please tell me what you think it took me 4 days to finish.
You may judge me,quickly commence.

Dang! This's like Haku on drugs, if you don't mind the comparison. I love your style, your facial expressions and colors are very expressive and vibrant. Although I really love the way you did the effects on the glass with the reflections and surface, the way you make make the blood is just... Wow, I love your blood style the most. This is a great piece of artwork. Oh, and how you have those surges of pain going down the victim's limbs is a nice touch!

The only thing about the picture that I think you could've done better, was the depth, If you had the glass curve out towards the screen (around the sides of the opponent), then the picture would look more natural and maybe believable for the sword angles.

Thanks I didn't think people would notice anything about the limbs and angles aren't what I'm good at.

It's still subtle, but it adds to the moment. Even with that one nitpick, the picture still looks great, keep it up!
