Tie Fighter - Cockpit Detail

Creating the detail on the front of the tie fighter was quite challenging, what I managed to do was create a pipe primitive stretch the faces to create a thin structural ring, I then duplicated this and shrank it down to form the inner ring along with deleting a few unnecessary edges to get the desired shape. Using the inner ring I inserted and extra face using the add divisions tool, I then resized the face and extruded this face to meet the outer ring and continued to do this for all the extra faces.
