Surprised that I haven't seen anything by Umika yet D:
One of my favorite AMVs of all time. Many Anime scenes used, with Oreki Houtarou (Hyoka) x Mio Akiyama (K-on!). Music 10/10, emotional impact 10/10, editing 10/10. Umika collab ZEVS1993
Also by Umika,
Not really an AMV per say, but the trailer for a AMV contest. SUPER Hype and I don't even make AMVs. I absolutely love how video was edited in time with the drum hits.
