Oh you work on Nidhogg 2? I've seen it in the news a lot; it looks amazing. That explains the incredible skill, then! 
Looking forward to see what you make next.
This isn't the 2nd piece I've ever done - that'd be much, much worse! I've been a games artist for a few years and made the switch to mostly pixel art about a year and a half ago. Lately I've been working on Nidhogg 2, which has been really good for my pixel art education.
Thanks Mandrill! ..whoops, my first infraction already! Think I fiixed it
Zombies are like onions! End of story! Bye-bye, see you later. (thanks!)
What the hell, this is only your second piece but you look like you have many years of pixel art practice! I love this. Do you mind if I ask where you got your pixel art experience?
Wow, extremely thoughtful cluster placement and colour usage. Already got my vote. Amazing piece.

Do zombies have layers? 
Very nice work! I love your colors and color clusters. 
The hue shifting makes lighting very beautiful.
What a style !
