Also I feel like maybe the color theming on each of the boxed outlines for the gens could be a gradient of the original games i.e. red to green, brighter red to bright blue, very light turquoise to pink, black to white, orange to aqua etc. but regardless the layout looks fine.
You should still have the logos in the middle. The fact it's to celebrate Sun and Moon and the 20th anniversary should be front in center.
On that note, maybe pic related would go well
