Credit Card Checkout Modal

Day 2 of the Daily UI challenge was to design a credit card checkout page/ form. Decided to go with a simple, yet heavy, Adidas style checkout form for a shoe.

I spent a little over my 1 hour limit, mainly because I had to trim away the background for the picture of the shoes. Apart from that I managed to stick within my limit.

Looking back, I'm not 100% satisfied. It could do with some more whitespace, and smaller elements. Also I'm not sure about the sidebar, I could've done something way cooler but I just don't know what. Hopefully it'll come to me more easily after I'm done with this challenge.

Let me know your thoughts and suggestions, I'm very eager to learn!
