Strange but interesting. I'm intrigued by the person sitting outside left of frame. You must have left them there for a reason, I'm just trying to figure out why....
I think you either forgot the "s" after produce or missed a ":" after Yoga. For a clear bright mind I would hope for a clear, bright picture without fog and all the distractions in the sand. The horizon may be intentionally crooked, but it takes away from the strong, capable phrase. This has a lot of potential, but with the above issues I can't vote it highly. Now with her in the same pose on a sunny day without stuff in the sand I'd rate it much higher.
I suggest the phrasing is too banal to be motivational- it's more of a commercial message. Secondly, why use a hazy shot to illustrate the "clear, bright" idea?
