To be honest, the emotion that communicates the picture, at least to me, is of an outrageously shocked angry person. This is something I discussed in another question: if you're going to use emotions, make sure they're unmistakably understandable.
With the above being said, the eye goes directly to the angry face, and there's no explanation at all at why is that guy so annoyed. Your text on bottom left is absolutely secondary and out of the flow, the box with the bars is pretty much a question mark, I have no idea why is it there and what does it represent in the context.
Finally, your site's name. Unless your site is fa.me (which doesn't seem to be the case), i'd be very cautious about using that element in such an outstanding way and position.
Now, on to your question: if you're dead set on using that image, remove the "engagement box" and place the main slogan on top of the image so at least there's an explanation for the image. This way, you'll get a dubious emotion, which is reinforced by the slogan. Users may think "i'd have used another image", but at least there's less margin for interpretation.
And other than that, your landing page doesn't have a CTA. as an user, what am I supposed to do with your page? What are your intentions?
In short: in all honesty, I'd get rid of that image immediately, concentrate on copy, slogan, content and user actions and then reinforce the message with something happier, like a beautiful girl holding a phone with an "oh yes!" expression (just an idea, of course).
And sorry if I sound harsh, is not my intention at all, just being upfront about your site
EDIT: what I meant for expression is something like , only that less "stock-y" and boring. Remember to always tell a story with your images, make them personal, connect the user with the site and the service (stock images tends to be horrible at achieving that because they're too general). Also, try to provide eye contact from the model to the user, or from the model to the slogan/CTA
