I gotta say I love how the Digimon are rendered in these Vital Bracelet shorts, this one especially.
While Sonic and Pokémon were depicted using hyper realism to try to integrate them into the settings or their live action movies, the Digimon are rightly depicted as CG models manifesting in the real world.
This is most evident with the digital effects that occur while the Digimon manifest and Bulkmon's Digivolution to Boutmon being depicted as a model losing its texture map before reshaping and gaining a new one, a depiction of Digivolution that's been around since the original PlayStation Digimon World and was notably seen in Tamers.
You get finer details in the close-up shots to imply a degree realism but not the uncanny hyper realism of Detective Pikachu or the Sonic movie.
