The light difference looks weird because its coming from the mysterious bottom of the sig.
Also the name looks pretty small and doesn't necessarily fit if you would. You did better with the background than last time because it was kind of dark. There are a few other problems of which I can't put my finger on.
I am happy that I am not looking and random splotches of light like in your old signature.
This one is a tad better but there is no flow.
