How does this look for an intro to an Application Portal? I feel like something is missing;
I love it. I like the introduction, color choices, application choices, and the name and the icon on the top right. Best of luck, great job on the overall introduction of the application! No improvement needed.
You should add a picture to make it look more interesting.
perhaps more aesthetic, like the colors of the union jack
Looks hot, like really hot, but why not trying using rounded buttons instead?
By the way, you can make player avatar rounded with the help of ImageMask module
