Ok I have reached the final phase of construction. I have primed all parts to checked for mistakes. As I filled up the holes with putty, there is a likelihood that the putty might shrink further after it cures. To cover up the gaps, I usually use dissolved putty. It is easier to apply and drys faster.
I have sand down and added lenses at various parts.
Did not do much to the shoulders except to add another layer of armor at the tip.
I added two more "fins" to each side of the armor at the back of the head.
After extension of the chest I need to scratch the "L" shaped details of each side. Saw some blemishes on this one, totally miss them. Sharp photos do help sometimes....
