nzr, thanks for your submission! However, we want to stay away from using imagery that looks like their initials. In our contest brief we stated "Please do not use initials or obvious dental imagery such as a tooth, toothbrush, smiles, etc."
I really like the work I've seen in your portfolio and am excited to see what else you can come up with. They are interested in seeing something "elegant", "professional" and "contemporary". It doesn't necessarily need to include a specific object or directly relate to the dental industry...it could be something more abstract. Keep in mind that we will be building an entire marketing campaign around this and the imagery in the marketing materials (website, brochures, billboards, etc.) will all have the necessary "dental" imagery.
Thanks and I look forward to seeing some new ideas! Westside Media
