As discussed in the comments, the forward section definately needs some armoured plates.
For this I looked at various existing models (like the FW Gorgon) and decided to use an slightly angeled model.
So I built some supporting beams, to which the plates will be attached.
Leaving room for the Light-AA's
Then I started on the central section with the new Imperial Eagle
More plates on the sides - again I used the 0.25mm plasticard, as this can be formed and bent rather easily.
