This looks super nice visually. I very much like the flat colours and simple designs, and how they contrast against the bursts of colour and more detailed drug / dream sequences.
Said animated drug / dream sequences are hypnotising to watch, especially with the music -- which I feels fits well all throughout.
Also, I feel the narrative was surprisingly strong. In particular, I liked seeing a father character portrayed as supportive and caring, with the moment near the end genuinely catching me off guard and making me a smidge sad.
Character poses were also very strong. It feels like great care was put into making sure everything looked visually consistent all throughout.
Good work. A real well put together cartoon indeed.
Fight On!
