From an all girl team to another, I think your site looks great!I love the color scheme for the site and the background. Robotics related but still classy. I also really like the picture for the banner of the physical sign. If you want to make it a little more prominent I could see adding some graphics to it (to put your menu on top of) and maybe a team slogan with some color blocking. Photoshop would be useful for that if you have it. I love your headers and the simplicity of the white backgrounds for the pages. I would look into adding more pages (which I'm sure you're doing).
Let me know if you have any questions on how to do things, I do our team's site and just made our new site from scratch: team3182.org. You should take a look
