Yes, the cockpit cover is from Kael'yn. The arms needed some filing on the fitting between shoulder and lower arm, but I the surface quality is good. The cockpit cover needed no filing (I only needed to decapitate one of the pilots and reattach the head a little bit more ducked into the screens) and the surface was very good. Overall two great additions which almost make my Stormsurge look like the Supremacy armor variant with the single big rail cannon. When I am able to finish the paint job I also plan to attach the secondary weapons (burst cannons, air-bursting fragmentation) on the torso similar to the Supremacy.
Any chance of building an alternate left shoulder-pad that flares up like those of fire warriors, and xv8s? I've been trying to work out a design by duplicating the left thigh greave, and greenstuff sanding but I'm no sculptor.
