Well I blurred it on purpose because i had an issue with matching the colors and i figured that this way you wouldn't really be able to see the color discrepancies
it looks really nice, the background and your choice of render looks pretty good, but the font I don't like, make it a little darker or add a stroke so we know where it is!
I am a novice, and I am learning as I go along. I will try to make my font more visible in the next couple signatures I do. I have some sweeet backgrounds that I made with no renders. I did the blurriness on the render so the color would match a little better, I didn't want it to stick out too much.
