Animation Assignment - Addition and Smoothness

In media today I re-did my animation and I had enough time to make it longer than the other. I wanted to make this one very smooth, so I could use some bits of this animation in my real assignment just in case they don't turn out as smooth.

In some scenes the LEGO floor would jerk around, the main reason of this was because I didn't have my double sided tape. I have purchased it but I had forgotten to take to the lesson. I needed to tape to help the floor stay in place, this will work and will make my animation look more professional and less jerky.
