Better than I expected
To be honest, I didn't expect much when I first saw this in the portal, but I was pleasantly surprised when I viewed it. The animation itself was quite simple and even somewhat crude which didn't particularly catch my attention, and I would rate much lower based on that alone. What really changed my opinion was how well the joke was carried out. The use of the theme and limited dialog text to demonstrate catching fever inducing illness in a humorous manor was beautifully executed despite the not so beautiful animation. With this being your first animation, I would definitely say that you have a lot of potential with your story writing if you improve your animating abilities.
