Clashing forces of opposing elements or facets of creation are always fun to observe and draw. The way the picture flows is very nice and looks natural but I think my only criticism would be to have the point of contact between them, the schism, be more pronounced or defined instead of blurred between the two. All that being said, I really like the piece. Water vs Fire, Light vs Dark, Smooth and Grasping vs Rigid and Sharp, all of this seems to be in this piece and it feels like it belongs there.
