Hi there,
Must of took you a good amount of time to make, they look great. I think it would help sales and buyers if you show the wireframe (quads not tris) on each lamp and even the lods. As if they range up to 28,000 verts I would like to see them if i was thinking about buying them for my game so I could work out if I had the budget for such feature pieces. You can display wireframe in marmoset or blender easily enough.
p.s I really like your Star Conflict, Monolith Remains
