I notice there's a house to the right of the Daycare that's South of Cerulean with no door on it, is that supposed to be there?
Also the Pokemon that haven't been replaced with a new up-to-date sprite should have something in there place until you guys get to it cause the Rival has a Kadabra on the S.S. Anne that hasn't been replaced despite Abra having the newer sprite for when he fights you in Cerulean.
