Isabella Hadouken and Isabella Masters?

Oh my gosh, I've waited such a while to draw this idea!  Another project for my fundamentals of design class, I was very inspired by the Tappers caricatures of those "twin" karate fighters.  I just couldn't stop imagining this girl and her alternate counterpart dressed as them, and now I finally had an opportunity to draw it out!  Like with my other drawings, I would've liked to color this, but once again, it had to be in black and white.  The reason why their eyebrows, eyelashes, and mouths look thicker is that I couldn't use much line, if any, so I had to draw them as long, thin triangle/waves.  [This girl and her alternate counterpart don't belong to me, but this drawing does. ]
