Most of the time when people talk about contrast they only reference the most obvious. Lights and darks. Colours and greys. You've taken that an exceptional step further and created a contrast in materials, between the ultra-reflective metal and the soft, nonreflective rubber material.
This is the most I've thought about something in a long time. Anyways,
Thats ok, always good to get other views on pieces you have done, I love how some people read into some of my pictures puts a whole new light on things. Re: 'Blue thingy' did it take you long to do that piece? Would make a good cat toy too!
