I have marveled over the work of Mike Maihack on this site before. His Supergirl/Batgirl comics in particularly fill me with joy.
Over on Twitter, Maihack posted a 'quick' Supergirl he did to test out some art supplies. That fast piece resulted in this. What a beautiful take on Kara.
There is so much about this that works for me. The headband adds a touch of 'Gwen Stacy' innocence. But the flowing hair is much more defined here, looking almost like a tidal wave. Really wonderful. The determined yet smiling face and the Matrix costume, as well as the setting amongst the clouds, makes this a big win for me.
Amazingly, this was done with 'cheap' watercolor as a test!
