Hello Jamie,
you may have noticed that the designer oleolego has withdraw his designs. The reason for this is about tracing existing artwork namely the cityscape which is stock vector artwork.
using stock or tracing any stock or image is in violation of LogoTournament policies. LogoTournament has an internal review system that takes care of problems like this when it arises and the issue was brought forward.
I like his work and in order to keep that concept in the contest I arranged to work with him and provide you an alternative idea that keeps the spirit of the design alive without any problems with copyright of protected stock or online images.
I hope my version is to your liking, if you require any changes please let me know.
Scott
