OMG! This is freaking AMAZING! The detail is impeccable especially that sky overhead and I just adore the way you drew Pidgeot I also have a version of Red (I know yours is meant to be Ash) and Pokémon; please check it out [link]
Cool!!! #1. Pikachu looks really small next to everyPoke else, #2. The stands are surprisingly empty, and #3. I can not imagine Ash, the same little-kid-disadvantage-using-impulsive-Aura-powered-Trainer, with a Team like this. But maybe it's in the future. Great job!
