You would benefit from having smaller images posted on here, people with dial up aren’t going to bother waiting for it all to load, try 640x480 images, maybe with links to larger versions.
Try experimenting with different materials, ie their specular and reflective properties.
Images are too big… so big you can see facets in curved profile 
The transparent materials are not ‘shiny’ enougth, and they shiuld have something to reflect to enhance quality
Keep blending
