Goin' retro? I remember you drew that old Volskwagen Type 2 (aka Kombi, Samba Bus) van, the first-gen model (T1; 1951-1975 in Brazil).
What makes this short so good? It has cold, authentic vibe of the pre-World War II (1939-1945) 2D-drawn animation with comprehensive, but not-so-clean sound that feels heavily compressed, and lack of actual voiced dialogue; the silent era of animation. Most importantly: the rubber hose style!
I can imagine if you animated one that inspired by the 1969-1990, the dark age of animation with low-budget, limited animation standard and target audience was kids, while the R-rated Akira movie challenged those unfortunate shenanigans. The short I suggested has rough, authentic vibe of the dark age-era animated motion picture with low budget, limited animations, intentionally childish tone, stereotyping, wraparound backgrounds, and maybe lazy-looking art style (Stylistic Suck).
