So I composited the two images of the ships.
I used the Clawmarks for the Details, and used the in game bitmaps as the proportions.
Notice that the height of the ship has shrunk, because the bitmap is much shorter,
I did however use the thruster size from the Clawmarks drawing vs the thruster size in the bitmap, but the thrusters stick out further back more like the bitmap, unlike the Clawmarks where the engines were closer to the body.
oh and I mover the lazer blaster things inwards more because they were hitting the other rectangular gun pod, but it still lined up with the image.
I still have some areas that aren't quite finished, i will try to fix those soon.
