>>20451630There's this .gif tutorial from the Overworld Sprites wiki page that outlines the way they should be animated, but as far as getting the style right goes it's something you just have to practice.
When trying to figure out what size to make things just refer to an official overworld sprite(s) of the same size and go from there. There are some oddities amongst official overworlds (like Kangaskhan being around the same size as Seadra, despite almost 4 ft. difference) so keep that in mind when looking for matches. I think the main thing is to just keep reasonable size progression throughout an evolutionary line.
