I was evaluating every entry by specific criteria. Depth, lighting, flow and overall concept are the main things in signatures. Overall concept includes: Text/Render blending/effects/color scheme etc.
Kluke:
Lighting - Whole piece is way too bright, would love to see more contrasted version, to improve lighting on your designs, trying working more on reflections, light sources/effects, try to imagine how the light coming from a light source would be hitting the render.
Flow - All of the C4D's just seem to be thrown in there randomly without any effort on arranging them to work with focal. (please correct me if I'm wrong)
Depth - I can see some blurred BG parts, which is good in terms of depth, it helps to imagine what parts should be closer to an eye, which should be further.
Overall - Can't really see much of render blending, since those are just C4D effects on top of the focal, color scheme is also a bummer here, I mean the main focal (render) is blue and you used brown-ish effects and BG, however, I do like your idea to draw out Sonic's claws with C4D effects.
Sorry if I seem too harsh :/
