I would...
- Extend the table the width of the ad (easy to do in this instance, just copy a section, paste, then transform it to stretch the width. Not a lot of clean up is needed).... crop closer to the elbow and rethink the type layout a great deal.
- Flip the photo - English is read left to right, so if you have an opportunity to push the eye back to the left, use it. (A note about flipping photos check anything in the image for text such as the doctor's name badge. You may need to extract that and flip it back, just as you may need to flip the iPad display back to right reading - I can't actually read any of it in the low res image).
- Utilize the red in the woman's top to create a visual "circle". This way the eye is pulled to red elements. This keeps the viewer actually looking at the ad longer. They see the URL, then the claim box, then the red in the woman pulls they eye up and to the right, not only leading the viewer back to the URl, but also upward right movements tend to convey "happiness" or "joy".
- Added the yellow at the top to create some continuity with what is below the photo.
- Enlarged the photo purposefully to break the yellow backing at the top creating more visual interest than a photo on a white background. In addition, if photos have faces, using larger images helps convey more "friendliness". If I had a higher resolution image, I may have tried breaking the woman's elbow out and overlapping the yellow below it. With the low res image posted here, that proved to be difficult.
- Minor levels adjustment to the photo to reduce the dark red overtone it contains (may have just been due to low res photo here).
Quick and dirty.....
If possible I'd change all the purple in the ad to red as well.
I'd also transpose the positions of the testimonial and the study, placing the testimonial on the right, and enlarging the photo associated with it. The testimonial is just naturally more compelling to people than a clinical study and the grey box on the right makes things feel off balance to me. I'd also try and make them fit 50% of the space. The study is currently wider than 50%, which may also lead me to that "off balance" feeling. The grey box on the left would balance against the larger photo on the right at the top.
