for #20 , this is a wordmark logo , where the brand name " impact " is easily read , yet with the face being clearly spotted with a smile = delivery the message of creativity, meeting productivity and leaving your client with a smile, as being happy with the results / productivity.
here #37 , i used the business tie and then the letter " i " curved to form two people, connecting at both ends, with their heads ( which also shows as the eyes of the face, with the tie being the nose and middle of face shape and a smile is there too )
let me know what you think.
Thanks
