Pretty good
Heh, for a joke piece I think you did well here considering how long it probably took to do the background anyways. Some parts of the lasers coming out from the back sync up with parts of the song too. What's the song called anyways since it sounds so happy?
The background is very nicely done and I think that it is pretty cool how it changes colors a lot and just goes through a cycled loop just like the clock character does as well.
The animation was smooth though so I have to give you that much for making a good looking piece of work that loops without ever getting annoying either which is great. Kind of trippy as well I guess since it repeats as it does. Kind of makes me think of the urban myth game Polybius as well without weird hidden messages added in to screw with your head.
The song you used is rather nice and I like how it sounds too, really cool but what is it called? Would love to know.
Overall, I think this is a great piece of work and despite you having to watch longer than five seconds to appreciate the art of it I think it turns out well. Cool clock piece anyways. I think the only downside here is the clock was only doing two things.
