Very good use of colours. Especially the magenta looks stunning and really draws you into the artwork. It feels like the centrepiece of the artwork.
Good use of shading and perspective you can really see and feel depth in this piece. I also love how you used bubbles added together with confetti like squares, they really feel like they act together and don't look distinctive because of their different shapes.
And I adore the minimal typography on the top and bottom, I presume it is meant to spell CAT, I like how it repeats the lines until it fades away.
