What Schlurbi said about the texture: try making a texture just like lib dread has.
On another topic, Karolia and Curios are right. A carrier shouldnt be very small (Geb is a light carrier if you think about it) and it is the size of a lib dread (if Im not mistaken), so, I think the sizes are just right.
Im curious to see a comparation with RH Battleship.
