Been there, like what you got going on. Lots of good suggestions by some very constructive peeps. I threw in my 2¢ and I'll check back for your next V. Cheers!
Why did you loose the 2012? I thought that was clever. Of course not everybody knows what it means, but still.
And indeed keep the stone look. Make it more grey again, less blue. keep the bodyparts in tones of grey and make the clothes coloured. If you'd like them to have an old look too you could make cracks in it like in old paint.
So try to make a vectorised stone structure. Make sure you have the natural lines and little stones, almost as tiny as sand, in the structure. Right now the structure is too big, like it's stretched out and that's why the stone look isn't coming off the way you probably want it. So the scale and depth created with at least 2 colours of grey of it is really important.
