It’s Tux! You managed to nail the shaping and its adorable quality. You even managed to have him holding his foot in a sticky sweet and cute way. I think because of that, the character is not sacrificed for your aesthetic vision. He’s complete and adorable. He’s the Lego version of a teddy bear. On that note, you also run the risk of over saccharine. There is a tipping point where too cute is too much (i.e. Ewoks.) This guy, however, has a balance to him that succeeds. I expect that these will pop up in cubicles everywhere in protest of Microsoft. Rightly so, I might add. I love the part usage for the feet, but I think the eyes need that easy going, laid back, heavy lidded look rather than the deer in the headlights fright. But all in all, it is a clever and cute and easily recognizable character. Awesome!
Excellent build. You stuck to your guns and didn't chase any of the mystery parts. That you held true to your vision is apparent by how astoundingly close you came to the original image. Well done. Attack!
Going with the cute angle, I see. It looks great. I especially like how you have him seated with his little feet sticking out like that, as well as the fact that he is an animal. That will make your build memorable as it is different than all the rest. Best of luck to you in the contest.
