I wasn't able to incorporate it in time, but users noted that having more sound effects playing in the background would help create a more immersive narrative for the portal page.
Users thought that background color changes would also help strengthen the message of the seasonal theme. Having subtle seasonal graphics also integrated within the background would also be nice.
Users liked the transitions between all the four different banners. Some suggested that the falling objects were a bit too small, such as the fall leaves. I plan on making the objects a bit bigger and also work on the transition animation if I have enough time.
