Man, its a mess of colors. Render serves no purpose to the whole sig. There is no flow. The coloring is very bad. I think the basic problem you face in your sigs is that they have no flow and its like u added the colors at the very last minute. I suggest use the colors more sparingly rather than cover the whole sig. Uptil now, i haven't seen any sig made by anyone who uses colors like you do. Restrict the colors to sustain the flow. Add depth, there is none in your sig. U see in the middle right hand side? U messed up there with the colors. Also there is no lightning.
First never even desaturate a sig an add colorful stuff unless u have an extremely good flow. Use the original colors, make a bg yourself using various tools, effects and brushes. From then you will see the sig coming into view.
I'm really sorry man but your previous sigs very way better

But you have a talent for this. Practice makes perfect.
