As your first sprite good. Nice flow, effects seems sometimes oversharpened, remove the text, it is distracting. Blur the background a bit more. The little x'es down there are not well put, remove em at all. If you want to add something like that, get your brush tool and brush little white dots. You couldve used some more C4D renders at the left. The wireframe is put nice. The right side seems a bit empty though. One last thing, if you want to color your signature a bit, color the render, too, or the feeling is a bit strange. The smudging is pretty good.
