Throwing in my incompetent 2 cents: the hair looks good and helps. But for the drops themselves, maybe there's too many, they're too unaligned with gravity, and too spherical/uniform. I'm not inclined to do an acne commercial demo right now, but I feel like not much water forms in droplets before skin gets moistened and breaks the beading ability. Sorta like you need more subtle streaks and fewer droplets. The light refraction should also be asymmetrical. I guess lighter on the bottoms, but not sure

But as discussed many times before, your ability is far above what I possess so this is all meant as constructive postulations. I really enjoy the overall coloring and shading
