And that's where I think it hits a more universal problem. Askari Nari is diverse, but the cover doesn't go all the way in showing that. An approach more like what Giraffes? Giraffes! does might be more appropriate, though in their case the collage is meant to represent their chaotic music style. (I don't personally like that artwork, but I think it's effective.) So I'd say either it should more aggressively represent the album's diversity, however you feel you can do that, or it should step back and focus on a singular, unifying personality.
....But I'm a programmer. I'm not a graphic designer. Take all opinions with an appropriate level of salt here.
