MUTO Evolution Theory

I think there just wasn't anyone of particular artistic skill in that audience and that was the best they could come up with.

Well, the resemblance to that original concept is still there with the current designs seen in the Mutos so far, just modified a bit to bear a little less resemblance to weird spider-looking things. I think it's a natural progression, really. However, when we first saw the Muto in the leaked Wondercon footage, it seemed to be a lot smaller overall in comparison to its latest appearance in the Asia Trailer. Or maybe I'm just not good with perspective. I don't know.

No.

The MUTOs did have some white on them. Since the artist was doing it entirely by memory, it's possible he thought the MUTO was all white.

First of thx for sharing my picture. No i didnt do it by memory, i just googled some fanarts and tried to make a realistic sketch using body parts of bugs and white spiders http://thrillerzillaart.deviantart.com/art/Godzilla-2014-muto-real-life-411050075
