It's better than the original but still not great. Here's some tips:
Research: Who is going to be viewing your site, what will they want to see, how will they want to see it etc.
Read the fundamentals of design: color theory, typography, layout etc.
Design to a grid: download the 960gs photoshop template and design to it, in your design nothing to aligned.
Change the nav, the buttons are horrible (no offence)
I think most it is basic layout issues, if I was you I'd tinker with some code, get to know the constraints of the browser and take a design from there. I've done a quick wireframe of how I'd set it out, every site you design I'd recommend starting with a wireframe, if the wireframe looks good then design will look good
