God........ what a disaster...
First of when you take renders... try and look at the quality of it. There are random bit's of the bg still hanging off and it looks very very poor. The actual background of the 'signature' is blank and empty.
The fonts are too fancy-looking and complicated, stick to normal and basic styled ones. Use default fonts.
Set the focal correctly, the render looks off and misplaced.
Same thing about the gun, it doesn't fit in there. Wrongly placed and it stands out of the rest, even more than the actual render and thus takes the eye off focal.
