well the Spida comes together quite nicely. I'm sure he will look stunning in the diorama, but even as a stand-alone he'll look good.
So after some more highlighting and detailing I added oil and grease stains around the joints and pistons.
They may look a bit strong on those images, but on the real model they blend in nicely.
This was after the first evening (2 legs and exhausts done).
Here you can see Teddy the grease inspector checking on progress :)
Here all the stains are applied.
Oily and greasy.
Then I outlined the icons, giving them a bit more presence on the Spida.
Then I started to add battle damage and weathering. First the dark grey basing.
