I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.

11 green marbles and 3 out of bottle.
The marbles outside look pretty good. The scratched glass container looks extremely fake. It seems like too many and uniform scratches making it look more like a pattern. I think you put too much noise on it.
+1 with Animaticoide.
I've watched the whole tutorial, and first, many thanks for the effort and the investment.
As far as i know, it seems that the scratches on the surface should have an influence on reflections too ... that it seems not be the case on the render.
Reflections seems to be intact, with no impact coming from the scratches.
Maybe use a shader mix node in order to suppress, or at last lessen reflections where there is scratches, may improve the whole effect ?
