I'm very new to sig making. Thought a good render might improve my whole sig result.

The background doesn't match the render.

Notice how the render is brighter on one side than the other? If you could create a light source from that area, that would bring a better focal point to the sig. The white light you pasted on the top left corner is not placed well. Your signature is a bit flat if I might add.

This is all adding to the Jakura's comment, btw.
