Hi you have put up very different guitar examples. Some are metal guitars others are rock, Les Paul.
What instrument best represents his sound. What does he or the band actually play?
Fender, Gibson, acoustic or a particualar electric model? I presume he isn't playing a flying V!

what you want to design a person holding a guitar like holding a gun sir

Yes, we had some non-typical or "wanted" guitar types due to the design they were in, or embellishments they contained. Specifically, we want an acoustic guitar either with or without the neck cutout for higher fret accessibility, OR a 1950s era Gibson Hollow Body Electric. He plays guitar, a Yamaha Acoustic (with neck cutout) A Martin 000-15M, and the Gibson

No person. Just the guitar and gun crossed. Gun should be an over/under double barrelled shotgun or lever action rifle.
