It's Ivy and her babies! (She is such a fun character! )
I love how dynamic the whole scene is.
The scene looks so lively due to all those little details like the papers flying around, people falling and glass shattering. I have one remark for the glass though. The edges of the shattered pieces could be a bit sharper to look more realistic.
I love the overall depth this piece has and how you use light and shadows.
