The colouring and most detail comes out really well in your macro and it's a nice diagonal positioning of your subject. It looks as though you've got a little problem of overexposure at the top of the centre link and lost some lettering detail from the direct spotlight. Always the tricky bit with reflective subjects. The background appears to absorb the light where it's caught in the spot so you might find aiming the light slightly off the chain and onto the background might give you the highlight you want, without overexposing any part of the chain.
