Ship Model Construction

In this lesson I have begun to make my 3D ship, I have had to change some design ideas such as getting rid of the arms and placing them as rockets. At the start I used a standard cylinder primitive and moved some face segments down, then I deleted them to make it look like a claw but I had to make some new polygons to fill some empty spaces.

For the ship I used a box standard primitive for the front of the ship I pushed some vertexes down and welded them to the ones below. Currently I am working on the wings.
