What is an artist body?

My work has been creating with natural elements in open places such as tree, rock, sea, stream, air, sand....and so on. Now I usually spend my body as some art stuff like oil colour, pastel and black charcoal. I realise that my body in the picture but sometimes not. I feel what my body is but not. I feel who I am but not...sometimes I am here but not. That is my recent work.
