Protagonist Busts

All four sketches will be cleaned and used on the Final Arcanum site, but I thought I'd share now. I'm still testing out the advantages of non-photoblue pencils, but they've been pretty sweet so far.
More on the characters:

Mirna Hawkins, 18 years old; she is the first and only daughter of Duke Hawkins of Rodenia. All her life she's lived comfortably and was considerably spoiled by her mother, but as she grew older, Mirna began to reject her cushy lifestyle and sought to rebel. She plans on running away from her home when, almost ironically, a band of pirates kidnap her and hold her for ransom. Duke Hawkins hires Captain Habersam of the Siren, a bounty hunter, to catch the thieves and rescue her. She appears in the beginning/middle of Final Arcanum and begins a shaky relationship with Acacitli, but I don't want to give it all away~

Acacitli, 17 years old; for all of his childhood, he dreamed of becoming a sky pirate, free to do whatever he want, so when the infamous Captain Clint of the Eurydice offered him a spot on his crew, Acacitli jumped for the opportunity. There he meets Zero, a mercenary working on the ship, and Selence Kite, another pirate, and the trio become close friends. He commits all his time and efforts to the ship and pirating and talks of nothing else, which also means he avoids talking about his past if he can help it and claims "It's really not that interesting anyway." He's the hero of Final Arcanum and one of my favorite characters in the entire series.

Ishmael Habersham, 22 years old; he normally goes by the nickname 'Mael' and is Captain Falk Habersham's younger brother. Ever since the death of their parents who were killed in a pirate attack, the two have been very close. Mael is the more passive and introverted of the two, preferring the company of books and a quite study to the action-packed adventure of the skies. Unfortunately, he doesn't have much of a choice when his brother decides to become a bounty hunter. He is actually very open-minded compared to Falk and likes to believe there is good in everyone, no matter who they appear to by.

Falk Habersham, 26 years old; Falk took the death of his parents much harder than Mael and took it upon himself to take care of his younger brother. Over the years, he developed a very strong sence of justice and determination, and became a bounty hunter in order to satisfy his need to hunt down every pirate in Khartes. He seeks to protect others so they don't have to suffer the hardship he and Mael went through. Though Falk can be a little blindsighted, he means well and (as long as you're not a pirate) he's very friendly and charismatic. He currently captains the airship the Siren.

YUP. There's some brief character bios for you guys. I'll try and have some more soon~
