here are my entries Hive account@knircky and Hive account@famunger and Hive account@steem-bounty
I opted to Leave things classy and simple. Logos are unique identifiers, just like names. The "S" shaped symbol on this design for me is Hive account@steem-bounty unique identifier across the world and web. Every user can easily identify it across any platform. It fits right into any sort of background color, thus making it very versatile, and UI (User Interface) friendly.

I hope my entry wins, and further, hope to establish connections with other steem users who have such needs as to get a professional logo design.
