Someone made the observation that it seems like they’re redesigning him to make him “fit in” to a world of humans to look less “out of place”, what with his long human legs and such. Which makes some kind of sense, but also tells me that the people in charge of this have exactly the wrong idea of what to do with Sonic. Making him more human is the worst possible approach to his design.
And as far as what they may have referenced, well… I think both deviantART and FA are good candidates. Especially the latter (possibly NSFW!)
