More fanart for Brandon Sanderson's "Mistborn" trilogy, from Tor books, the text largely says it all. This started out as a little loosen-up doodle that got complicated on me. Click "Download" to check it out a little larger.
I confess, I did not do the proper research (going back into Book 2 and pulling out all the Koloss descriptions), but rather relied on memory and the impression I recalled from reading the book. Hopefully I didn't get it too wrong.
-EDIT-
So actually, I got it pretty wrong on a couple points. The current version now more accurately reflects the skin color (a deep blackish-blue rather than a pale blue) and their proper size ratio. That'll teach me to do my reading
first. *sigh*

Little less than an hour on the sketch, and then maybe two on the paints and layout. The text is pulled from the Glossary in the back of the second book (wherein these guys appear) and paraphrased from characters within the main text. All done with the Intuos 9x12, lines Manga Studio EX and paints/texture in Photoshop CS2.

I think the Koloss only have one type of sword, though.
This is my first and oldest illustration of them, and if there's one thing I did entirely wrong here it's those swords (both of 'em). I've done several more koloss illustrations since that are more accurate. They appear in The Mistborn Adventure Game, and now that it's come out on the shelves I'll have to see if I can get some more pieces up online.
It's definitely a favorite of mine. Four books out so far, and more to come!
