These are all my latest sigs, unfortunatly most of them have a black border which doesnt show up on this dark skin, anyways c n c welcome - 1. 2. 3. 4. 5. 6. 7. 8. 9.
Some of these are good and have some potential, but work on the text and depth. You can also gete rid of the borders.
Most of your sigs' borders are taking away from the overall sig, that goes the same for the text. Also, try adding more depth and better lighting.
I like the third signature most I think. Overall it are good sigs but you need to work on your text like Sexiom said
