I did watch your Chomper video to the song "Eaten Up Inside", and felt that the song and the video didn't seem to correspond very well with each other. For instance, at the ending, you put in a happy scene where Chomper is rescued, yet the song is still singing "eaten up inside", which is in sharp contrast to the scene because the song itself isn't very happy at all. Another part I felt didn't fit was near the end when Spike shows up to save Chomper, again a happy moment since we know Chomper will be rescued, the line "let me die go away, I never got what I wanted, I never got what I needed", which is again in contrast to what's going on and what Chomper actually wants.
There were some parts that seemed to fit, such as, in the beginning, when the sharptooth stampede occurs to the line "And fade away". I felt the way this line is sung corresponded pretty well to the movement of the sharpteeth, sort of complimenting each other and when Redclaw shows up to the line "I never got what I wanted", which seems to fit Chomper; I doubt Redclaw is something that he wanted.
But overall, the video just feels rushed, and, while I like the song, I don't know if it really fits Chomper all that well. When listening to the song, I am under the impression that it's about someone who has gotten so frustrated with their life that they are willing to kill themselves. This doesn't seem like something Chomper would do and the video itself seems to contrast that suicide message at the end where Chomper willingly allows himself to be rescued, since he didn't actually want to die.
It seems that you only have the episode "The Lonely Journey" to use footage from, which is pretty limited, forcing you to use only a small amount of clips. My recommendation for you is, if you would like to make another Chomper video, try to get a hold of more episodes so you won't be as limited as far as footage goes.
As for an mv, I would recommend going with a song that may fit Chomper a bit more, and also be aware of the emotion the characters are giving in the video. For instance, if you want a serious song, try not to use scenes where the characters are smiling too much because that kind of ruins the mood of the song and contrasts it.
I hope you didn't take offense to anything I said. I was just offering some feedback on what I feel could be improved upon. I'm not trying to insult you or anything.
