Not quite good. Did 당신 even put any effort into it? The song doesn´ t fit with Hellsing, but I 당신 wanted, then 당신 could make it okay. Most of the scenes are not well chosen for the song. 당신 even repeat few scenes A LOT which is annoying in a normal amv. The timing is poor, though sometimes it fits with the song, but mostly not. The only thing I can praise is the idea to merge this song with the anime.
