After countless re-uploading of my animation in various video formats and with different settings (including suggested by YT bitrate & resolution) I gave up and decided to keep it at Vimeo only, where there is no difference in quality between my original video and the one visible in the service. Here at YT the quality is visibly lower, even on still images as above. I have no idea what way others achieve a good quality picture here, I can't. So, find me at Vimeo: http://vimeo.com/sirielle

And yes, the poor guys discussing the case are my sketchy Caranthir and Celegorm 2009, slightly touched up yesterday for the above footage purposes. None of the faces in these animations tests are my final take on the characters anyway. Greetings!
