I struggled with this one a little - I found it quite difficult not to detract from the shelving and to keep focus on what the images were about. I tried to avoid the typical library setup that was widely used and approached it from more of a "new shop opening" while the furniture was still being assembled.
Did I succeed, who knows?
In the end I was happy with my final renders but I did not place anywhere. The interesting thing about this competition was that the owner himself was very active on commenting on the images during the competition.
Here is my thread on the Evermotion site where you can see some wip.
