I like it, but I would watch your proportions. Like her arms are a bit too short and hands too small along with a few other things. Some of which may be on purpose since your doing a manga style.
I like the ship too. Maybe add a bit more shadow and highlights to give it a more three dimensional depth.
One other thing, make sure the ship and the girl are standing on the same plane. it will give it more weight, especially the ship.
It's pretty good though... and I need ten more words so umm have fun
