I can't read or write Cyrillic but let me guess what it says below the password box with my ultimate guessing skills....my master skill which I acquired through hard training...tells me that it's says Forgot Password ?
Actual Feedback : Really nice I like the clean design. Possible Adjustments : Make the Text Google colored like it is in the Logo of Google. Adjust the border of the username and the password field so both are same. As I see the username field hot a light thicker grey border and the password field got a thin dark grey border.
