[WIP] Spacies [Fullconversion - Looking for 3D-Artist]

[xxxxxxxxxxxxxxxx]

The second texture is definitely much better! In addition to what Statyk already said, I think you could improve the metal parts a bit more, by making them look more worn and less "pristine". Think about where the metal would get scratched the most - the edges for example or the places where two metal parts scrape across each other.
Put light scratches there and make those parts really bright on the specular (but not on the gloss!) to give the impression that the patina on the metal has been scratched away there.

You could also put some rust on the legs or maybe have some dried blood where the leg of the creature meets the metal.
