OK, I'm going to plunge in here since no-one else has said anything. Your thumbnail looks really good, because of the compression. When opening it up to view the full size image, unfortunately is looks too pixellized and immediately loses its depth and form. I think you were probably trying for a cross stitch effect? I don't know the answer you need, but I imagine the reasons I've given are the reasons no-one has commented.. Don't be put off, but I think it would help if you put more form by means of shading back into the picture, which would give it definition and depth. Hope this helps...
