The logo was actually the 9th submitted in the 99 Designs contest that I ran, out of a total of 160 submitted designs.
The designer is Alexandru Parvulescu from Azanti.
I've overall had a good experience with the 99Designs process. I will shortly start a new design for the cover of my first book. I would recommend it to you if you're looking for graphic design work, and using my 99 Designs affiliate link you'll get a free $99 upgrade.
