It's actually a guy and a girl. She is Hera and he is Akut so everything is a collaboration. I just choose to focus on her! But yeah it's not cheap. They sell the majority of everything they put out. Sketches start around $900 and small simple 10x10 paintings start around $1,500 but I would say you need a good $3k-$4k to get a really awesome piece.
I finally got a chance to stop by the gallery last night and check out the show. It is even better than expected. They do so much on each piece you would never be able to see in any pics. They do hand sticthing on a lot of them that just looks unreal. Seeing all these things in person just cemented the fact that they are one of my absolute favorite artists.
