Nagastiel and Dean - watercolor

So, I was trying this tutorial by bluekomadori and I might be in love with this coloration technique?? I'll definitely use it again.

The pic features Naga!Castiel and Dean from my Unlucky Explorer and Solitary Naga series.
Cas' pattern is based off an eastern diamondback rattlesnake.

This work is already posted on Tumblr. Please reblog from there.
