I think in both of the above renders (jamminwolfs and bevans), the figure is still blending into the background. Both probably could work if some DOF was applied or the background blurred. For promos, generally you want to make backgrounds neutral so that your product takes the focus. 

As far as Tina's lips: I would try to smooth them a little bit more. I do have a head morph with a similar lip shape; I used zbrush to smooth it out to make it a bit natural. 

Also some tweaking of the facial expression can help sell the promo a bit as well and give your product more personality.
