Packshot Nebbiolo wine

Hope you like it!

Done in Blender v2.79.1: Modelling, Lighting, Shading, Rendering and post.

very nice packshot. Congrats. The onlyflaw i notice is on render n5. It looks like the bottle mesh is not subdivided or smothed enough. I can see the quads geometry in the shading.
Was this a commisoned work or personal practice ?
