This is a challenge for me. I normally don't have a problem with water drops, but the intensity of the red and having some drops in the shade, makes me a little dissatisfied with my efforts so far. I have only added a couple but I need to make sure that there is a little spot of light in the right place to give the appearance of glistening. The ones in the shade are more subtle., as the presence of the water changer the tone of the colour underneath. The shadow of the drop also needs to be in agreement with the light direction.
