I suppose in regards to the theme of the short, I appreciated how blunt it was towards drinking water. The message is at least clear there and I can at least appreciate the minimalistic approach to this, but things visually could use a bit of touching up to appear less lifeless. The tube-like limbs for the purple cat doesn't exactly radiate an eye-catching design and feels more like an obstruction (The color choice clashed with the background as well). What appears to be a dune/beach area in the beginning, although maintaining a visual consistency throughout the rest of the short, seems very plain. I think it's somewhat applicable to the last shot as well. I did think, however, that the motion graphics on their own were pretty solid. Also, I would work on the audio mixing as well. An example is the final line of the short where the audio appeared to break/peak. A bit of audio leveling would also help too since the beginning and ending cuts were very loud in comparison to the main animation.
All-in-all I think it's passable in terms of its theme and I think it could've been expanded on a bit more, but some technical touch-ups and visual adjustments would be best in the long run!
