i did give him advice. i told him that a 45* rotation would inhibit his playing, and that a possible better idea would be for him to do what inspired him and get a kirk hammet or whoever style guitar and do the "carved faces" idea which he said he liked as well
positive criticism: why dont you make the deisng into an ML type guitar? obviously with the metallica star, a star shaped guitar should be in your best interest. try coming upo with a design which incorperats the ML's balance, and add the jaggedness similar to that of the symbol.
possibly when you are done you could bevel the edges and paint the silver, and then the entire thing would resemble the metallica logo.
