Pull out the colour so there is less yellow/blue. If the water was very deep where you couldn't see the bottom (where it would almost look like a black pool) then you would have stronger colours and a more visible reflection (eg. sunset on a lake or harbor buildings on a river), but if the water is shallower ie. your pool or a puddle, then the show through from the bottom surface would make your image not as strong; a lowered opacity (as you have done) and paler reflection. This is presuming that the liquid in the pool is water, if it's blue liquid then it's fine being blue. Water isn't blue though, albeit some creative license lets you get away with it so it's not the end of the world, but the blue is created from the scattering effect of light; the deeper your water the bluer it looks, so it would depend on how deep your pool is supposed to be as well

Sorry for going all Bill Nye on you, it really does look good if you leave it as is and your colour pallet for your entire dungeons light sources has been very intense and vivid anyway (dont read this as a bad thing, I think the lighting effects you have done look amazing) so could match the style, but it might be worth having a play with it.
