I wouldn't suggest posting old stuff to the release forum. It doesn't reflect you as an animator, but people people might see it and instead of checking to see what you've made more recently, just not bother and move on with their day. Since you made this a year and a half ago, I'm not going to comment on the animation. However, did you use film for this? I noticed the time codes on the bottom right. There's nothing wrong with using film to brickfilm (other than it's super impractical), I have plans to make one in the future; but if you have the urge to do so in the future, try to avoid those time codes.
