If you would like a logo done - I have a friend who might be interested in doing it for some advertising on your website (he's just completed my new logos which will be up in the next couple of weeks YAY!)
Also, I recommend going to yotophoto.com and getting some pictures of happy smiling people for your header. yotophoto helps you find the free pics that you can use without creditation, etc.
I also think that the links on the left hand side should be put into a box with a black surround -- just to clearly show they are a seperate section to the middle part. Maybe even a bullet or similar infront of each link aswell
"Enter Acne Free Guide => " Make it bigger and stand out more! People love free guides and stuff -- especially on something as horrible as acne -- so be more bold with what you are going to give THEM for nothing.
One last thing.. I would also suggest a "Contact Us" page. So if there is something they can't find on the site, they can contact you for more information
Oh oh! Even.. a newsletter so if new information is added to the site.
The ideas just keep coming.. haha!!
If you need any help with the stuff I've mentioned, be sure to send me an email or MSN msg
amieetheridge@hotmail.com and I'd be happy to do a bit of a deal so I can help you

(No cost involved)
Cheers and hope I've been of some help!
