Daily UI Challenge #001_Sign up page

Hello everyone!
I have been lurking around dribble and finally uploaded for the first time. I was always self-conscious as a junior designer that I wouldn't be good enough to upload anything on dribble.
I just started Daily UI Challenge for self-improvement. The first challenge is the sign-up page. Any comments and criticisms are welcomed! Some nice comments would go a long way too :) Thank you!
