Strobe photography

Today while I waited I started reading about strobe photography...nothing more that using proper lighting to take a picture
Seems simple right....I don´t think so.
So hre is a shot I took of myself......a selfportrait...I am holding the flash above my head to my right....I took the shot using my Nikon D90, at a 125 of a second and f22 aperture....55mm.....pretty cool shit!
I will have my stomach removed tomorrow
I am doing this to release stress
Cheers
