Hey can I give you some constructive criticism?
I love how you've only rendered the faces really.. and left the drips to shape the rest of the area you're painting on. If you tinted the rest of the paper underneath the faces where the bodies would be.. I think the drops would stand out more as an accent rather than really drawing your eye away from the face which is what they're doing now. You want to focus on the face.. you know? not the drops.
These are great though..
