SaaS Login Page Design

I think you might be able to remove the 'login to your account' text at the top and just say that on the button. The button seems active before any text has been entered and I think it should remain slightly inactive until the fields have been filled out. "The Register Now!" text is yellow on a grey background which makes it harder to read. There is no hint text within the form boxes and this is a missed opportunity to educate the validation required. "Enter your Email Enter /Your Password" Could just be "Email" & "Password" to save some repitition. The little illustration at the bottom is nice I think it could be bigger on both mobile and desktop to add visual interest.
