Concept images for a mall atrium

Hello,

I am participating in a design competition for a mall atrium the due is in 2 days. I have done all the resarch and have created the concept. I need someone to help me to create 2 images to represent nicely the interior achitecture concept.

The dimentions are 12m x 25m, it opens for 8 floors, it has a glass ceiling.
I have for you as a base: the cad file of the plan, the basic sketchup to represent the volume, and mood images for each design feature.

It is a design competition: i have passed the first stage to be selected out 20 participants, now there will be a selection out of 2 participants. If we get selected we need to produce the 3d rendering and develop the concept I will invite you for that ( the budget will be 2500 usd for your rendering and design development work, now at this stage is only 300).

I am generaly used to work in different scale/volume projects and this is why I need someone who is familiar to work with larger spaces to join me. The schedule is terribelly tight, I have done all the major design work, I just need your help to put it all together in 2 nice concept images to include to my proposal - once we win this stage all the nice work will start.

Please have a look on the attached pdf with some information to help you understand the requirement.
