Line, shadow, texture. The only problem was focusing on that tiny wire. And it is plastic coated which didn't help at all. It looked golden in the sunlight but when I opened the file on the computer I discovered that is actually rusty, and the rust is not evenly distributed so I converted to black and white. Apart from the "golden" wire the conversion made little difference to the colour of everything else. C&C welcome.
