Neat, my commission's here! Really liking Akko's face and expression here, but Diana's face looks kind of...off? Like it doesn't look entirely right. Also, on the variants where Akko isn't smiling, they're blushes look kind of muddy? Like the shade of red doesn't work that well on their skin.
Hope that doesn't come off as offensive. Overall this looks good, just some things about that don't look all that right to me.
