I think it's a bit glossy, unless it's meant to be like cellophane ?
Also I think it's a bit too universally see-through. Most transparence/translucence is most apparent where the material is tight to the underlying form (i.e. bones and other protrusions) and more opaque where it's hanging off (under the breats, between the legs). Also things are more opaque as the curve away from the viewer, while most transparent as they become flat to the picutre plane. More opaque where light falls on it and more transparent where light is coming through.
in all though a great study
