I kinda liked it!
At first I thought "Okay, this is going to be boring -_-'.. "
But after a while I saw the background changing and I saw a lot of new stuff.
I really enjoyed it. I loved the music that you've used too ^^
You should make a series out of this.
A turtle with a mouse on his back on a journey, meeting new people and discovering things. The mouse and the turtle are very different from each other (the mouse is fast, the turtle isn't. The turtle is kinda big, the mouse isn't at all). But they don't care about their differences, they are just good friends on a journey. You don't HAVE to make series, but if you would I would really watch it!
Good job!
