100% I know its much too early to request this, that's not the point. I actually really like your go on the sprites in order to get so many. It really is a clever balance of Quality and Quantity!
Though I'm curious if maybe it'd be viable to get help from multiples of people.
modeling 400+ pokemon is no task for a single person, but maybe volunteers could help. whether its a team or someone offering to model so many pokemon?
