As mentioned the Imperial Guard is all about ornaments and Imperial iconography. And since the ATHENA is one of the Empires finest pieces of warmachinery, there need to be many icons and ornaments.
So what would be better to protect the forward prow of this fine ship than a large Imperial Eagle?
But not a standard eagle, no it needs to be something big and really impressive.
So the idea was to build a layered eagle, and I cut 3 layers of 1mm plasticard for this. The first large layer gives the complete outline. The second layer shows the legs, chest, and inner part of the wings. the final third layer shows only the chest and top part of the wing.
