Linda and Ariella..from Peter David's Supergirl storyline "Many happy returns.". Ariella is the daughter of Linda Danvers (A Metahuman version of Supergirl who isn't related by blood*) and the Silver Age version of Superman. the original line art was produced for an auction to benefit Peter, who recently suffered a stroke but is on the mend.
Pencils, inks and colors by me, with a little help from my wife (and critique) Karine Igle.
*She was human, got superpowers, became Supergirl.
