Ever Blue

Everblue is a fantasy/adventure webcomic by Michael Sexton, set in an endless ocean sparsely populated by a few floating cities. Luna, an introverted young shipwright, was leading a quiet life in Rose City until Ten's flying boat was accidentally shot down and she is roped into helping him build a new one.

This webcomic provides examples of:
 * Action Girl: Luna was raised in a military academy and is perfectly capable of defending herself.
 * After the End: Maybe... there are certainly ancient cities sunken under the ocean.
 * All There in the Manual: Among the old voting incentives, a small wiki and comments under each new page, a lot of background information about the world has already been explained.
 * Arc Symbol: "Black Candle" emblems can be seen on flags, banners, and even peoples' clothing in the background of certain pages. No official explanation has been given as to what these symbols mean, though Word of God says they are important.
 * Art Evolution: Not so drastic as some other webcomics, but the comic switches from black and white to color within the first few pages, and the shading gets more detailed later on.
 * Bandage Mummy: Clara, although it's not used for dramatic or comedic effect.
 * The Bartender: Lampshaded
 * Blind Seer: Clara. She might not actually be blind but all the bandages she wears can't make it easy to see.
 * Book Dumb: Ten can't read.
 * Cool Boat: The Skyward, Ten modified it so it can fly
 * Early-Bird Cameo: Dagger, who hasn't appeared in the story yet, can be seen on wanted posters in the background. Clara also appears in a crowd scene a page before her official introduction.
 * Et Tu, Brute?:
 * Furo Scene: Luna has a rather tasteful one with surprisingly little fanservice.
 * Hard Work Montage: Used when rebuilding Ten's boat.
 * Heroes Want Redheads: Luna's hair is a pretty shade of red and Ten clearly has a crush on her, so this trope seems to be in effect.
 * Iconic Item: Luna's red ribbon and Ten's bandanna.
 * Meaningful Name: Ten can mean "Heaven" and he owns a ship that flies.
 * Ocean Punk: The main setting.
 * Pajama-Clad Hero: Luna in Chapter 3 during a rainstorm, which results in a Wet Sari Scene.
 * The Pollyanna: Ten. Tragically optimistic.
 * Refusal of the Call: Luna
 * Suspiciously Specific Denial: Luna isn't singing banned songs, nope no singing here!
 * Underwater Ruins: Luna has explored the "city core" which is underwater and completely off-limits.
