Look man, the animation isnt that bad, I've definitley seen worse. But really the movie portal should be reserved for things with a little more content. If this was 10 seconds longer, had any form of audio, and a narrative it would be respectable.

I know you probably put some real work into this, and were eager to show it off, but your future projects will benefit a ton from just putting more time into your work. I don't want you to get discouraged by a bad review, because I think that given time you'll probably be a decent artist.
Just spend more time on your projects, and add some audio (even just music would be fine).

Final note, if this is a WIP and part of a longer animation I really think you should finish all the parts and post it together instead of individual scenes.
Keep on tryin man, I wanna see you get better!
