Overall it is pretty nice. I would just remove that red vertical light because it seems not fitting if the whole signature is blue and there comes out of nowhere a red stroking line. If you wanted to use it to improve the coloring then I would add some more and maybe even make the color a little stronger. I dont like that hard shaped form in the background, that it suddenly goes diagonally down. The focal on the c4d thingy is good, just a little bit too bright. Be sure to lighten down the lower part of the signature a little bit and remove that line, it just looks odd. :>
