I'm not familiar with Torchwood, so I didn't read the fic (I make a point of avoding spoilers for series I plan to watch one day), but you had me at Smashing Pumpkins' Bullet with Butterfly Wings... Though I feel that it's a little out of place between Strange and Umbrella. The song after Umbrella also seems to be a bit too jumpy for the rest of the mix... but both songs don't really hurt the feel of the mix, even though it's a short mix, so I guess that's fine. Your artwork is also nice, simple but cool; I wish I had the talent to make something like that... Anyway, great work here! Congratulations!
