It is a fanime and it shows, but not in a bad way. Here is somethings you did well:
-You keep colors and art consistant
-The atmosphere is bouncy and fun
-It feels like you have a passion for this story and that is amazing
Here are the things you could work on:
-The lines, it suffers from what I like to call: Ms Paint syndrome. (Lines that are pixelated and crude)
-The animation is the weakest part since it doesn't have many frames and is repetitive.
-Lastly, the character expressions, they don't change for more than a few times, especially the mother which scares me. I don't demand that they change every moment (that's impossible) just that they move more frequently.
Final Verdict:
It is pretty okay for a fanime. The character designs are indeed charming and so it the idea. We all got to start from some where and this is a pretty decent one/
