V1:

My first pop-up sig:


My first request sig:
V1:
V2:

And here's the others:

I like your first attempt signature as well as the first popup sig.

I think the quality of the renders don't look that great in the signatures. Was that the intended effect?
And maybe bold out the fonts a little

My 2c opinion
