I'm getting started on drawing all the new Sword / Shield Pokemon. I'll be drawing them in the style of my analysis art. Here are Grookey, Thwackey, and Rillaboom.
In terms of design, these Pokemon are almost great. I like Grookey a lot. It has a lot of personality in its design. I don't like Thwackey. I really hate its color scheme and it would be cuter if it had a semblance of a neck. Rillaboom is pretty neat. I somehow knew that it would have a musician theme and it wraps it up nicely. The only thing I would maybe change is make its forearms more muscular so it looks more like a gorilla.
Rillaboom will be a lot better when Grassy Surge gets released. The obvious comparison to make is Tapu Bulu, but Rillaboom has access to U-turn and Knock Off, two moves that Bulu could have used. The rest of its movepool is kind of shallowvand its Speed is lacking, making it Corviknight food.
