I like the text in both of them. Background effects are pretty nice too
It is very sharp but I like that
The only thing that bothers me a bit is the color.
In the first one, it seems a little bit boring but I'm not sure if I like the colors in the second sig better. Maybe a bit( the left side of the second sig is cool) but I think it could still get better though I 'm not quite sure how.

But it's very good indeed

 

It seems like a fine job in photoshop, however I just find it to be lacking something. Personally I like your current sig better.

 

The render is shit Jon. And you told me, If the render is shit, The sig is shit. The dude looks like some Saturday comic reject >_>

 

I prefer the second one, but without the text.
