I adore Dionysus' art and characterization. I have seen his interactions and really feel like that fits the original Greek mythos very well, too.
Poseidon... I think it might just be because of the main picture of him, the angle it comes at, he looks odd to me LOL but I do love the colors
Aphrodite, though, like.... her art is stunning. I can really feel like, "This is Aphrodite" when I look at it. Same with uh, Artemis. The art is just so damn good in that game, you take a look and can immediately go "oh that's xxxx god, that's aaaa goddess"
