I still think you could work on the text.
It....stand out too much, and doesnt suit your sig.
How about putting it as a dark grey with dark green first letters on the right? Or maybe a very dark green and then a lighter green as the main letter you are pointing out.

You have changed a lot since your first sig. Chapeau to you.
I still think the render needs a tad of blending into the background. Just a bit; gives it more effect.
