VivziePop's sketches are scattered across multiple platforms, but her YouTube channel is a goldmine for early concept art and rough animations. I stumbled upon her 'Hazbin Hotel' pilot years ago and fell down a rabbit hole of her gothic, hyper-stylized character designs. Her Tumblr used to be active with WIPs, though now Instagram and Twitter (X) seem more consistent for doodles and updates. The fandom Wiki archives some deleted posts too—I once spent hours comparing prototype designs to the final 'Helluva Boss' characters!
If you're into behind-the-scenes stuff, Patreon might be worth it for higher-res sketches, but honestly, her public posts already feel like flipping through a chaotic artist's sketchbook. That energy where every line oozes personality? Chef's kiss.
