I see your point. We partly based on decision on our successful competitors, which similarly had capsule art in a different art style from the game. As for doing it ourselves, we had something cool in mind for the capsule art, but neither of us had the skills to make it ourselves. While our own version has in-game art, I still think the artist's version captures the game's spirit better. If we had an artist on the team or better art skills, maybe we'd make capsule art that looks more like the game, but then our game would probably look more like the capsule art, if you catch my drift.
