I would shrink your pics a bit if I was you. You paint very well, but I think pictures of this size drop marks rather than give better marks (unless a painter is good enough to be top 50). If you shrunk it by a third we'd have a better idea of how it might look (it's a 28mm after all) and would still be big enough for those who prefer big pics. But again, really nice work, especially the contrast. A lovely face too.
