This is really sick. Love how the geometry of it, especially the tails. It gives a hint of reminiscence of Mayan art, which itself is part of the Sonic art DNA. For me that sort of brings the gang into the continuity of Sonic Adventure and even Sonic CD (thinking about Tidal Tempest). I also like how Vector pops out of the enclosing shape a little bit, seems fitting for his personality. I didn't even know about the Casefiles thing - I don't follow Sonic happenings too closely these days, but that sounds pretty fun so maybe I'll check it out. Anyways, yeah, really well-designed piece!
