Here's a recent drawing DC commissioned me to do for a stock cover art image. It's a team of villains, I believe, led by Deathstroke. The guy in the middle/right side has tattoos that come to life.
I didn't use any photo refs on this drawing, though the female character is modeled after my fiancee, Tamara;)
Note to art collectors, the original art will be going up for sale.
