How to edit rebel face maps?

Does anyone know how to edit rebel face maps so they have bangs sticking out the front of the hat. I tried using the smudge tool on the group_03 erdim (Male 09 rebel model) to make the front bangs stick out (I just overwrite models in my gmod) but when I went into Garrys mod it didn’t work.

Oh and heres a picture of the edited face map. (I saved it as both a .jpg and .Vtf)

1: Smudge tool = bad idea. Try using clone stamp or similar to a separate layer
2: You don’t have to override models or anything like that, just stick the .vtf file in the right directory in /materials

Smudge makes things look unrealistic.
