I'm actually pretty shocked to see a nice quality, well edited Sonic X video. Every time someone edits a kids anime an angel gets it's wings
Editing wise I really liked this. There were some nice transitions, the scenes were synced nicely and you made pretty good use of the show's kinda limited animation. You definitely made a more effective, serious Sonic X video than I would have expected! But personally I think the video lacks something to really tie it together. In the beginning I thought it would maybe be a romance video or a tribute to the girls since there was a lot of focus on Amy, the pilot girl and Rouge, but they more or less disappeared from the rest of the amv. After that was somewhat random with characters popping up without any buildup in the middle of the video and then
maybe showing up once more later. Like I said, I liked the scenes and found them fitting to the music but they needed more of a theme to really pull things together, maybe that would mean not giving focus to as many characters? To someone familiar with the series like myself I think it would work just fine, but I can see newcomers being pretty lost.
That aside, I enjoyed this a lot and will definitely be watching again! I really appreciate seeing a good video with an underused source like this and hope you keep it up.
