well then in that case, I guess the rating is fine if it stays moral :3 There are people in this world that wear little of nothing, and it is completely nonsexual :3
There is no nudity in this comic. Although the native Islanders in this comic are topless they are wearing grass skirts. Do you HONESTLY think this strip could offend ANYONE? Get over it. I've got a good story to tell here which should be read by people of ALL ages.
Nktakumi - I don't see why the artist should bump it all the way up to mature... I mean, as long as it stays like this. The nudity is not really sexual, it's artistic and essential.
I think an E rating is fine for right now, but maybe to be on the safeside, bump it up to teen?
