Not a big fan. B/W against the blue and cyan colors doesn't flow for me. Some good FX but sloppy. Text is good, but I hate the stock/render. It looks like a lifeless Asian girl's head and neck is floating, and she has yellow lips, another color to clash. Not your best. Intermediate 1.
I personally say scrap it and move on. I'm not a huge fan of your sigs, I like your medium and large art better.
EDIT
Just found why it looks sloppy to me. Top right corner, the black c4d looks terrible imo.
