001 sign up page

Few months ago, I tried to do the Daily UI challenge, I was totally novice in prototyping. Today I saw what I did and yes, it was not good at all. But it was the beginning, today I tried to do again the sign up page.
I really want to improve my skills so please, do not hesitate to take 1 minute to give me some feedback, it a good way to see and fix my mistakes. Thank you !
