Nice,, But there are numerous things you could improve
+Great effects
+Good lighting
+Contrast is very good
+Depth
-Colors (you mentioned this yourself. You could maybe choose different colors, i personally don't like all the blue in this sig, its to much
Also,, I can see some green and purple c4d,, delete this,, it messes up the sig in my opinion
and i don't know if this is my screen or something you did,, but the dark parts almost looks brownish/red,, i would love to see this in black
-Size, In my opinion the sig is to wide.. you could shorten this a little bit, because the c4d on the right draws to much attention away from the focal
-Originality, It doesn't have that wow-factor.. I would love to see some new FX
Yea,, sorry if i have been a bit harsh with the CnC,, but better to be honest than lie and say there is nothing wrong with it
I would love to see a V2!
ps. DEXTER ROCKS!,, can't wait for season 7 and 8!
