change the top logo and header, u can use roll over effects on menus to make it look better. bottom part looks ok nothing wrong with that
The header photographs are a bit too cluttered.. try using just one nice high quality photograph instead (with colors that are not too saturated)
Your headline is in a nice spot. My eye went directky to it. It could use a tweak: Start Your Career Advancement Start Your Career Advance Your Career But, that headline only applies to half of your target market: job seekers Employers are left out. Try to think of a headline interesting to the type of workforce to which you're appealing -- ladder climbers, high tech, low tech, disgruntled
Looks very professional. Maybe review header... less focus on the medics as not to scare off non medics.
