This build appears to me to be demonstrating an effective way to recreate a nicer looking Vulture Droid compared to the original LEGO model. By using similar parts, Inthert made his own model that is a simple cross between old and new. According to the builder, this Vulture has lots of articulation, including each leg and the ability for the head to pop up and rotate for more poses. Inthert also explains that it is very fragile (though it doesn't look it) due to the extra articulation, but I think that's a worthy sacrifice. I'd still have several of these in a Clone Wars diorama. Well done!
