A great blend of beauty and the pirate lifestyle! Not to mention that this illustration is kind of empowering to the women who had to disguise themselves as men to be pirates.
The woman here looks beautiful and powerful, which is awesome. Also, you did a great job of putting in common pirate tools, such as her sword, hat and telescope. It does a nice job of showing that a woman can be a pirate, too.
The background was well drawn and has the raggedy pirate ship look to it, which is perfect.
Excellent work all around!
