there's almost nothing to say about this, it's just a badly drawn character tweening onto the stage, a couple of skews, then lip syncing for half the video, then he turns into an angel and it's him just standing there for the rest of it.
You could have done more with this, ie use a bit more of the song, experiment with more movement in animation and allude more to the "hidden meaning".
To improve on the character, I'd recommend drawing more people from observation and photos as well as learn construction so next time the characters look more interesting.
Otherwise: i don't get the purpose of this, I believe a lot more effort could have been put into this before being put on the portal. Please try more next time
