Daily UI_Day #002_Credit Card Check Out

Second challenge: design a credit card check out form or page.
I decided to draw a credit card from scratch and try to make it look as realistic as possible.
I also thought about a simple ui, complete with all the information fields and the option to go on an pay or go back and add a new credit card.
Please, let me know what you think about it! :)
