Wow, super amazing job! I really love this little adorable animation <3
The lighting really looks cool without making the background look lazy with how minimal yet detailed right where it needs to be.

Even though I animate, I'm nowhere as good as you, so take my criticism with a grain of salt, I guess? The only things that really bother me are how bouncy the girl's hair and skirt are and the boy's anatomy. I feel like her hair would be bouncy to some extent, but I feel her movements wouldn't really cause the skirt/hair to bounce and flow quite that much. Mostly the skirt when it flairs towards the boy.

And as for the boy's anatomy, I feel like his body is a bit thin. The girl's too, to some extent, but it's a bit more hidden with her arm and her turning to the side at the end. That part is mostly personal style, though.

But seriously, especially for a sketch animation, it looks absolutely amazing! I hope you're super proud of this <3
