Still Life - Step 4

Still a bit of tidying up to do with my shadows (the bottle's shadow is not the same direction as the jar's) and with the background curtain (not quite sure how to fix this - I think I need to simplify it, rather than render every fold in the light fabric). The 2nd picture, with the original setup and the photograph shows the colours better, in a more natural light, but do bear in mind that the painting is of the still life in artifical light, coming from the top and left, not with light from the window at the back.
