Just painted for fun. I painted gems on the armour to give it a weird eldritch feel, rather than just straight techy sci fi. If I painted it again I would add another colour to the armour, perhaps yellow elbow pads... or paint the gun green...
The mark on the tail gem was a hair that got stuck in the varnish. Always seems to happen on a focal point, and only to character minis, never to rank and file......
