Bach Fugue 2 from the WTC in 12 tone style

The second fugue from Bach's Well Tempered Clavier written in a serial 12 tone style. I usually spend more time ensure that there aren't any (or little) parallel fifths, parallel octaves, direct fifths, and direct octaves, but I decided it would be more fun for you to comment on any that you find. Let me know in the comments how many you find and where you find them!
