ok here is my go at C&C:
Good:
-the text is well put together and i can tell that your developing a nice style.
-good light source
-vibrant colors
Downers:
-Your composition is a lil weird and all you can see is his head in the corner...
-i dont like how you made that yellow to the c4d on the right a straight line... it completely ruins the flow
- the c4ds ontop of the sig are pretty sloppy
i would give this sig a low average to a mediocre rating.

:p
