it's also a stock, i have both.
That said to the CnC:
The render is over used, however you did okay with it. I do feel like i've seen this sig a billion times though, pushing the line toarwds generic.
The c4d is okay, but i'm not a fan of the radnom clipping mask circles. Also that random square thing in the right of the BG is really distracting and nees to be 100% opacity or taken out. Half way isn't working right now.
also lighting could use work, it just doesn't have any glow,.add some white to it or something to make it really pop.
not bad though.
