Critique #1: (Get to Know Your DNA)
I really like your background image, but I think it would be better if it were larger, or did not tile awkwardly as it does right now.  Also, I think the text would look better if you restricted the width of the content pane.  I think the concept of trying to give an introduction to genetics, and using that to inspire readers to try out the various products out there is a great one.  However, one question I had after reading your site was, what is the difference between the two products that you advertise?  I would be interested in what brought about the price difference.  On your page on the "Potential for the Future", I think it would benefit from a reduction in paragraph length and the addition of subheadings.  Overall, great job so far.  I'm especially looking forward to your Genetics 101 video.

Critique #2: (A Runner's Ally)
I like your concept of a site oriented for a wide audience of beginners and professionals.  I think there definitely is a lack of online resources especially in terms of running techniques, so I am looking forward to your site.  One thing I noticed on your front page is that the subheading "Ask yourself a few questions:" was the same size as "Welcome" message.  It might look better if you reduced the size of your subheadings, so it's easy to tell what the big messages are.  I especially liked your summaries under each of the sections.  I think they really help capture attention.  However, it might help if you reduce the width of your content, since otherwise your lines will be very long.
