Hello!
Fun concept for a One Piece amv. However, I felt like the AMV was mainly wrapping up all the sad parts of the anime with no real link between them. It would have been cool to have a deeper reflexion on the atmosphere you wanted to create.
On the technical side, I think your color corrections were usually too much over the top and the blurs were especially intrusive. I know it was kinda needed to alter the overall atmosphere but the wash-out effect was too present imo.
The rest of the editing was quite good in its own, the song is respected, so yeah, in conclusion it's ok but needed a bit more restraint on the color changes and more reflexion on the scene selection.
Keep it up!
