well its pretty cool but i think the render is oversharpened i would add a lightsource on this one and somethign to make it flow but gj on the sig ^_^
the text could do work the placement isnt thet greatest!move it aroun and play with the colours a lil. the c4d on the left kinda sticks out and dont flow with the sig so maybe take that out or do sumthing blending.Add more adj layers maybe and try adding depth to the sig,
