Thank you for your submissions, ysonmez. I like your concept but I am not crazy about using the silhouette of a face. take a look at these links, they are examples of some logos I like.
Thank you for your resubmissions. I feel that the silhouette of the faces do not communicate the message I am looking for. The lines and angles are a little too sharp. My suggertion is to soften the angles and limit the design to 1 face. Thank you!
