sonic has changed over the years... anyway, i like this sig, it has great flow the render is bleded nicely also
It looks a bit trendy. Old style trendy as well. I like the effects but I don't like sonics contrast and color over the background's, looks a bit low quality as well.
The render blending looks feathered which is old-trendy and has always looked low quality. Good ways to blend the render so it looks part of the image is smudging, C4D, actual effects, or sometimes if you can do it right, you don't need to blend it at all.
