No seriously, on my screen the wireframes from what i can see are the frames going at the same angles and lines on the frame the same.
Maybe my screen is to dark but thats all i can see from here.
But yeah your sigs have been 80% the same with different renders/text/colour for the past...
Not bad, same style as 70% of your work though.
It also looks like you have just through in the render over your rihanna sig with new text/no colour.
The wireframe looks exactly the same, unless its my monitor making it dark so i cant see it all.
