Daily UI Challenge #1 - Login Screen

Hi! This is my first shot on Dribbble. This also part of my participation on Daily UI Challenge. This shot is the first challenge, "Login Screen".

The main point I want to put in this design is simplicity. I tried to make use of the Golden Ratio to measure the spacing and the font size. I use gradient button for "Login" to make it stronger than other buttons ("forgot password" and "signup"). Althought this not perfect, but I really enjoy the process :)
