>>5744344think of it as bending a transparent/chrome object but bent in an organic shape with a scattered surface.
because of it's form and the motion, it will pull the refraction of what's behind it with it. and because water is highly reflective, high contrast highlights and shadow from the light source helps sell both the form and texture. pic related.
you would apply the refractions of the object(s) behind the water splashes where its mid tones would be located. your pic demonstrates that already.
