Good signature Ben :y: I can see that you are improving the depth by adding c4d's over the render a little big so that's a big plus. Secondly, I notice that you have done well not to make it monotone, however does the colours compliment each other? Honestly I would say it could be worse, but could be better. The text is also better in this one, but I personally don't really add text to signatures (just the way i am).
Overall big improvement mate :y: I hope to see more improvement in the future
