Nice references overall.
Swimmer looks just like the sprite from the games. Seems like his Slowpoke knows Surf, so I guess that's not the prize HM for this race.
The Pokédex seems to be the in-universe way of checking the opponent's HP as we see it in the games.
Honey used as a way of luring out Pokémon was implemented as a mechanic in gen 4, although you were supposed to cover trees with Honey, not Pokémon. Now I wonder if this manga influenced future games in any way...
