I really like the use of the C4D at the bottom of the sig and how you blended in the text. Thats some nice work however, the c4ds in the back behind the focal are too soft for my taste. Looks sort of blurry and liquidy which in my eyes didn't work out too good. You have good colors in one of the part sig, which being the front but else where its not really working and feels a bit dull like in the back behind the focal. Work on it and KIU!
