Hi there,
The scene looks very convincing although a bit dull. Perhaps you can add some spotlights, color variation and a different camera-angle to spice it up a bit
I notice a bright white line underneath the glass frames probably being scattered by the glass. It almost looks like some caustics effect. Can you clarify this by telling what lighting setup you've used or perhaps someone else who can clarify this behaviour?
Instead of chamfering you can also use the "round edges" option in the shader setting of your material.
