Barbara (aka Babs) Tarr is currently the artist for DC Comics' Batgirl. Along with Cameron Stewart and Brenden Fletcher, she redesigned Barbara "Babs" Gordon, aka Batgirl, to much fanfare in 2014 and created the exclusive cover for the WonderCon 2015 Program Book.
Babs Tarr works almost entirely digitally. The initial sketches were done on the computer, printed out, and inked on Bristol board. The final inked piece was then scanned back in and colored by the artist in Photoshop.
