The reason it's blockier is because it's somewhat based on the shape of the rook chess piece, which is less streamlined than the other pieces.
In this ship? In TPT. Well, it must be bigger (it is a cruiser), more streamlined (look at the bishop) and use something else than photons for the engines. A reactor is also much needed.. That way it will look better. The weapons shouldn't be photon based.
I feel that you guys have lost interest in this ship.
Changed the engines. They output more photons, thus more power. However, they don't come out straight.
Give it much bigger engines and weapons, this should represent the rook in more ways than name.
Also, if you're wondering what those little marks along some of the sides are, they are measuring marks. I put them every 3 pixels on those sides.
He is at least starting to make an interior. For the engines, I'd suggest layering tmp 1 cray (cflm) with fray. I'll show you the idea.
Perhaps something other than phot engines.
