It is a pretty nice signature. You really are good with your smudging and effects, I just think there is so much going on it is a bit distracting. I like the colors, especially the top one (top pic is much better than the bottom one). Great job with the text too! I like a lot about this pic, it shows a lot of skill, I would just recommend making it a bit more passive and less dynamic, NOT MUCH or it will change the pic too much, but a little bit to make is less distracting and easier for the eyes to enjoy. Also, the size is a bit odd, too big for a sig, I don't know really what to call it besides an image. Overall, great job, I really like a lot about this image, let me know if you update it, and the top one is the better of the two.
