I know they already have one but no one else thinks it looks extremely Bounty Hunter-esque? Look at the engines, I can definitely imagine the hunters, who I think originated in Texas, basing a big bad cruiser/BS on Liberty design?
Really love the ship though, good frame.
Oh and if you wanted to play off of that idea, just make a vertical extension from the bottom or top, like the original Piranha?
Edit: About making it more "Corsair"; I picture corsairs using more of a winged ship so heres two options:
1. I know it might prove ineffective in combat, but see how this ship is segmented into three parts? Take the middle part and cut it up from the center and bring it out like wings? I've no idea how it will look but it might give it a more 'sair feel?
2. Hell take the whole thing and gut it like a fish?
3. Take a look at the Praetorian and use a more rounded style like on the edges of the wings there. For example on the little winged parts on the rear of your ship. Maybe as like an armor style? Need to be rounded though.
