Interesting idea, but still needs some finishing touches in my opinion. The text for example, looks bad left in the corner, you could've made it the focal point but now it just kinda takes your eyes away from the sig.
I suggest you try to get more distinguished shapes and contrast where you want the viewers to focus on, and then blur and darken the rest.
I tried to replicate the effects and the style I have in my current signature, but I don't know if it worked out.
Hehe, it's my eye
