TBH i dont like it one bit.The background doesnt match the render.The text isnt that well either.All i can say is try another render and try using diff fonts.Also try to blend in your render/stock more.
Slump majorly. THis piece overall isn't that great, honestly. The blending of the stock is dreadful. Depth sucks, flow is weird, and the text is better without. Have you tried smudging your stock in? Duplicate it and smudge it. Use your blending modes too, that makes your layers appear more or less exponentially. The BG, you could probably fix easily. Apply the image and burn out the outer area's of the sig. I suggest a // flow pattern here. C4D's can help. Sharpen up the main focal as well, it needs it... XD Don't be afraid to blur/sharpen if you have to.
