I like the contrast between the fluid liquid droplets and the stiff upright letters, which is also emphasized by the color contrast. I find it interesting how the d breaks the border of the droplet. It makes the word look less contained. The vibrant color choice leads me to immediately think of water and seems to make me thirsty.
