This video is really good! Although I guess I've got a few things to mention, I've started using 60fps myself and I think you need to be better with scene selection. I'll admit this is far better than I think I got any of my videos to look, but try to leave scenes with text out and use a logo remover or something that works with virtualdub. (ie. http://www.compression.ru/video/logo_removal/index_en.html
Otherwise, really good job!
EDIT: Also I'm unsure if you used Twixtor for this or pre-interpolated your footage, but if you haven't already I suggest trying using avisynth and interframe.avsi which works with svpflow. This way you can interpolate your footage using the "animation" preset and it works in realtime too if you wanted to watch it back and stuff! ;o;
