I'd have my teeth redone, and lower canines replaced with long metal fangs. Vampire style has been done too much...I think, more 'orc' would look neat.
And I'd have the eye fixed that has taken so much punishment over the years. Always seems to be my right eye that got it, when trouble was brewing. My missspent youth involved too many things like knocking conkers out of trees with home-built grenade launchers (well.....it was more efficient than throwing sticks..launching a half pound of magnesium/chlorate or permanganate flash in a metal can, using black powder or just about any old organics suitable for nitration...only one time the launching charge was a bit TOO big, and blew the fucking back off the thing, right in my face while I was sighting it)
GHB synth that overheated in my teens, and flash boiled solvent/caustic and GBL up in my face, that very goddamn picosecond i chose to adjust my mask and scratch the end of my nose.
Accidental reflection of a laser, thankfully not too powerful, and not tuned to a horrendously damaging wavelength.
And god only knows what else I've forgotten about. My right eye has shite vision from anything more than a few inches away its a blur when trying to read. Couldn't read the opticians chart, other than 'its stuck on the wall over there..I think....'
Laser surgery would be great.
