Very good! Thanks for your work. Your logo has a lot of what we are looking for: subtlety, sober, elegant.
A couple of comments: - Is it possible to play around with the silhouette? It looks great already, but I wonder what kind of variations you are able to bring - Is it possible to pick a more elegant font for the 101? Other logos have very nice fonts (with very round "o"s). I don't know how good that would look on your design, but it'd certainly be worth a try.
