I am really pleased with the overall effect of these pieces and think they go together really well as a triplet. The shades of grey work really nicely and the finish of the paint has come out really well as well.
As I am planning on lighting these forms from the inside getting the light to radiate outwards, I have covered the bottom of the pieces in aluminium foil to maximise the light reflected off the bottom of the forms and thus outwards from the form. Below you can see the coated bottom of the pieces. I actually really like the effect!
