real good job following megan fox's tut!
I like the text,
just not the light in the top right,
if you did render/lighting effects.
try changing the layer mode to lighten or something,
for it to basically change the lighting through the whole sig.
overall though, 6.5/10
nothing against your sig, its just your light source ruins it,
in my opinion.
btw, good clipping mask for your text,
i can never seem to make mine look that well :/
edit:
if you have the PSD saved,
try and change the px of the border stroke, to 2, instead of 3 or 4
I think it would look better, also another opinion :]
