CoffeeGo - A Coffee App Ui Design

I did this Ui project without much knowledge of Ux, and now I realize the mistakes here but still I love the way it turned out exactly how I intended to design it. The coffee selecting buttons would rotate the coffee menu arch and the preview would change with a spin transition. Couldn't really add a transition preview video, but here it is. My first Ui Design. A proof that without mistakes you can't improve.
