^The best Sonic has ever looked imo... Not just that render but I mean his current Unleashed/Colours/S4E1 model...
If I could change anything I'd knock an inch off of his spines. But as it is, I think it has the best of the old and new. He has the stumpy small look of his old model with out the stupid pot belly. The sideways grin is back instead of that angry look they were giving him for a while. The shoes are perfect, I even like the slight wear and tear. Much better then those trainers they had him in for a while... fuck that.
I also LIKE most of the new additions, I think the green eyes actually add to the character and make it a bit more interesting and I like the way his ears kind of look like horns. Also, another subtle thing I like is how his legs are thinner at the top and get wider as they go down...
Also he seems to be a lighter shade of blue since the Adventure-Sonic 06 days.
Another thing I like.
