I'd change the font in the input boxes to be different to the rest of the font on the page. Its unclear whether they're static text blocks or input fields unless the user does a little clicking. Some graphics wouldn't hurt. Take three steps back from the screen, half-close you eyes and see if you can figure out what that page is about when you look at it. Until you get that 'at a glance' information happening there won't be a whole lot of user response.
The combination of your color is good the text and the background. Regarding to your content it's do not place properly it's little bit messy.
I like it try to: add a third color get a cool/funny icon for your logo or do a new logo if you can afford it you could use the same font size you used on "Remember me" text, on username and password fields see how that works out.
