The Necormancer's Toy

So I started reading the third book in The Demon's Lexicon" series by Sarah Rees Brennan today and in the second chapter three of the big characters get attacked by a creature composed of a random assortment of bones all held together by ribbons. I just had to doodle him out, so I decided to do a quick speedpaint before bed. It took a couple hours since I had to look up some of the bones, though I didn't try and get them all completely accurate since this is just meant to be a quick concept.
I'll do another inked black and white piece for the book as well, once I finish it, to go with the two I have already made for the first books in the series.
Any feedback is appreciated! And I highly recommend you all go pick up any of Sarah's books, they're all amazing.
