Tie Fighter - Added Detail

Being a bit unhappy with the detail on the main body of the tie fighter I went back and had a look at my schematic and saw that I could add something to both the top and bottom of the model. Using the booleans difference tool I cut away at a sphere to create a small dome shape, I then further cut into that using some modified cube primitives to create the parts shown below.

I also added some minor detail that I saw on my schematic image onto the pylons leading to the wings using a few cube primitives and mirroring them to fit as needed.
