I finished the ball turrets last night, the last pieces were the sensor lenses above the gun barrels.
So the last bits are now all in, I will start painting the freehand and logos tonight. Planning to do a large freehand raven on the top surface, with the regular blood raven insignias on the sides in front of the ball turrets.
Here is a MOCKUP of what I plan to do. I'm excited and nervous as all hell at the same time, because I haven't done a freehand piece as large as this before, and I am not sure it will even turn out any good :)
