Maybe something more, something 3D along the lower lefthand and bottom sides. Could add necklace of small glass spheres from Alpha Stamps to main nymph? Put iridescent wash over all but nymphs, so they remain clear and glossy? Seems to need to be under some kind of layer–looks too raw to me. But I want to keep the difference of the women from the rest of the piece. Maybe put glaze over the nautilus and matte gel over the rest excepting women? Include an interference blue in the nautilus glaze?
Also could experiment with circles of white paint–it occurs to me the white of the water & foam on the nymphs isn’t carried through the piece. Not sure where to put the circles, though, because I really want to preserve some of the open space between the nymphs and the cameo. Maybe larger ones over the lower area and a few smaller ones in upper area? Will have to experiment on a duplicate image.
And still would like edges to look a bit more finished. What if I glued small mosaic tiles in blue shades all along edges? That might be quite nice and actually be in keeping with the whole water theme, since I associate mosaics with baths.
