How to draw a Hydralisk

I can't draw, but I've always wanted to. For me, one main reason for why computers are such a big part of my life is that they enable me to the impossible - in this case, draw my favourite Starcraft-unit, the gut-wrenching Hydralisk.

This post is partly a shameless act of self-promotion for my new and (yes, I disclaim it openly and fully) commercial blog, but also an honest question to you guys what you think of my work. I have recently started writing Photoshop- and Illustrator-tutorials for the Blogatize-network, which is something I cannot do at my main, eSports-focused blog. In the first article, I go through how I drew a conceptual image for a tshirt-print - meant to become part of the growing wardrobe of A Certain New Site.

Feel free to check it out, tell me like it is - does my image suck or is it worth a damn? Is the tutorial, despite its length, helpful and read-worthy or just plain boring? Feedback is king!
