Well then, they will probably dislike this one even more Abdulrahman - Hectic Harmony - which is from this weeks shoot.
Most defiantly this picture will come across as natural to most people and they will never imagine the process required to shoot it. I would imagine it would not be the most impressive of your collection, yet shooting a space like this is a lighting nightmare that only a professional understands and appreciates.
Still, they are kind-off fun to do - and may just help to get our point across to some clients, that images like this...

.. don't just happen - when it comes to quoting a fee.
Therefore, I think you can impress the viewer with this picture. If you limit your presentation to 4 pictures you will make a lasting impression. I suggest four pictures in the following sequance:
first picture randomly posed and composed
second picture in the final position
third picture with all styling elements in place
fourth picture with full lighting applied
You might want to add a fifth picture with people placed in the picture to show the difference. I think if you present this brief sequence you will impress everybody and more important not give out your trade secrets, unless of course you don't mind that.
