Cavewoman in progress

Ive actually finnished this painting, but Ive yet to get a picture of the finnishe pice Xd the finished one shows her whole body, with some cave paintings on the wall behind her i quite like this half finished look its got though what do yous think?
This is done with acrylic on greyboard, byt the way. a little charcole was use in the backround and to sketch the lines for the woman.
