'Realistic' Sonic the Hedgehog (v1.2)

Ah, a drawing based on live-action Sonic. Never thought I'd see something based off that on the internet that isn't memeing or mocking the hell out of the design.

Design-wise, you managed to actually make this version of Sonic have it's cartoony design roots AND look realistic, something the model team honestly didn't do all that well. The fur looks like fur without going into the uncanny valley, the eyes manage to be fitting without also going into the uncanny valley and the shoes actually look like something I'd find in real-life design-wise while still being evident that those are Sonic's shoes. Not to mention, the quills, while still looking realistic also manage to be quite similar to the style of the aforementioned hedgehog's in many of his official artworks.

The posture is also another thing that I find is great in this picture, since it looks like a cool pose that the cool, blue hedgehog would actually do, both in the games and hopefully in the live-action movie, as if he's saying "Bring it Eggman!"

All in all, I can't really find any real faults with this drawing. If you wish to draw similar to this, perhaps with another Sonic character, I'd say go for it. You show that you have the capabilities of doing so.
