Dalek Targetting Drone - rusty

Here he is with the black washes on and the first of the rusts.
Go to go in next and give some "depth" to the rusty bits then try to replicate what looks like axle grease that seems to be leaking out of joins and plates on the Specail Weapons Dalek.
Then put the eye in.
I've got that all ready in Gloss Red but, i dunno. Thinking the bright red might be TOO much of a contrast to the rest of it, so i'll do a Gloss Black one and see how they compare
