Second this, D's compliment the shape of your face very well. Try and stay away from B, the square sides accentuate your nose a bit too much (even though you do have a lovely nose!)
Very cool resource and there are some great tracks here. I'm excited to see how you expand the library to accompany all kinds of different projects, even beyond games.
I'm quite a fan of royalty-free music, actually I just finished up a project using 100% royalty-free music from Kevin MacLeod (http://incompetech.com/). He uses a creative-commons license for all of his work, but makes the bulk of his money through private projects brought on from exposure.
Our project was for an immersive reading experience for The War of the Worlds, which meant we needed lots and lots of different types of music for all the story arcs. Shameless plug if you want to check it out: http://e-mersiv.com/apps
Again, I think you could definitely have a market for more than just game devs out there, your pricing model is attractive enough to be used for short videos, ebooks, etc.
C and E are very nice choices as well!
