He's about 3.5 inches tall.
I choose you, Psyduck!
I'm pretty pleased with how he turned out. I used #10 crochet thread and a size 7 hook, with ecru, black, white, and yellow (not sure on the exact color name, unfortunately) for the colors. It took me almost exactly 8 hours to make him, which was very convenient. The pattern (linked above) was pretty easy to follow too. (I like her patterns a lot.)
Now on to the next project... we're working on our steampunk goggles some more tomorrow. Hooray!
