I was trying to draw them older but they somehow turned out as shotas. I just wanted to draw merboys and get rid of some paint.
I was trying to aim for a Yin Yang theme in this picture, hence the strange poses. The dark side is nearest to Haruka even though he is seen as the good guy and Rin is nearest to the lightest side even though he is seen as the antagonist. So there is a little bit of good in the bad guy and a little bit of darkness in the good guy.
I'm about to ruin it.
The paper was just too big for the scanner, so one side looks darker.
Just kidding, I did try to be a little deep there.
