>>41166165Biggest advice I can get as a graphic designer is have the main Monster be something cute and cool at the same time. Pikachu works so well, in fact I would argue is the greatest designed mascot of all time, because it appeals to both girls and boys, it's cool when it's in action and adorably cute when it's not. I would also highly recommend looking at "Comfy" art for promotional material, you want a world people would actually want to live in. You also want mascot Pokemon to be easily chibified. This makes it appeal more to girls for merch as well.
It's cool you're here though saw the trailer for the Switch, at least someone is trying to take on Pokemon.
