Recently on his blog, he has posted a couple of commissions which I thought I would share here.
One thing I like about these little webcomics and commissions is how Maihack is able to showcase the differences in approach to super-heroics between the two heroes while making it feel completely natural for them to be friends.
Here a more serious Batgirl looks over her shoulder while Supergirl flies by smiling. I think Maihack's Supergirl is always smiling.
I will also say that this commission is a little ... um ... cheekier ... than usual Maihack fare. There is a sense of coy 'come hither' from that Batgirl.
Maihack also posted this second SG/BG commission here: http://cowshell.com/2013/01/28/batgirl-supergirl-commission-2/
I like this one a lot. It has the feel of a post-adventure moment of zen, Kara elated at victory, Babs just soaking it all in. Again, smile abound.
I can only hope that Maihack makes it to an eastern seaboard comic con so I can meet him.
