First of all, I'd recommend you to not to put text in the avatars, the empty space isn't meant to be filled with text, it just makes your work untidy. Second of all, the dimensions for using the signature don't match the original ones so better make 475x150/175. I really like that signature, the text is okay with some simple lightning. What I really liked was the stock you chose for making the signature, easily made the focal there. Keep up the good work!
