The face is painted very smooth and with a lot of skill. It looks very classic. Is it from life or from reference? Have you studied the old masters? Which technique did you use for the background? I like the soft red and green colours on it. They are very bright but not too saturated as well. That is perfect. The hair and the background are from an other (artificial looking) material. As if she is looking through a gap. At first glance I had an association with the plastic wrap filter from photoshop. I wonder what is behind that 'filter' I think of a green garden. Then I thought it looks like a modern icon. Which is very original. I wonder if the details in the backgrond have a certain meaning. I see some hands and drops but unfortunately I cannot look at this full size. I think I would prefer the foreground and background to be more integrated. I think then the painting would be less striking maybe but the woman would look more worthy to be in a more natural environment.
