The filter makes the render look terrible. The cloudy background suits, but the whole signature has bad colours. Use c4d's and brushes in your sigs to make them better. Also, try making them larger too, so you can fit in more texture
yeah looks like you just took a fur brush and smudged the whole thing...
i like the right side of the background, you should have added more light, but thats just my opinion, i would have approached it that way...
but then again this is your 5th and its actually pretty good for that early...
V2 is definately better. The brush on your stocks body though is kind or irritating to stare at, and a little distracting. If you wish to use the brush, do it a lot lighter. Otherwise, it looks much better than V1, and would make a pretty good sig.
