An impressive piece.
I love how the white glowing eyes jump out at you in contrast to the brush stroke style of the hair. The texture of the clothes, especially on the sholders of the jacket is exceptional. The background, as well, can not be faulted. Neatly drawn and with just the right amount of blur and warp to give the image the right feel.
The feet/shoes of the zombie seem a little rushed compared to the rest of the piece. A minor flaw but one that stuck out to me, also the blood splatters around the sword and stomach feel flat compared to the rest of the image.
A well deserved 4.5/5 stars.
