Not digging the border thing at the top and bottom. Render placement is a little weird too. Other than that, it's quite decent. Perhaps consider depth a little more in your next piece.
It just looks like you shoved in some noisy c4d's..Dont use noise unless you really know how to do it. Also, you've made like 8 sigs from that render, get a new one, and take out the border, and the text is the exact same as it was with the first one. Sorry to say, you havent improved at all.
