Yes true, you image lacks of diagonal lines and remain too flat.
But what hits me the most (in good French that I am) is 1) that you call Champagne : Wine and 2) that you put the cork (and hum not even the original one) on the bottle.
This makes me feel that :
1) You drink alone (Y not 2 glasses, Champagne is romantism, so let's make it 2 glasses)
2) Once you have served 1 glass then no more, bottle closed already !!! Pianyi !!!
Just my 2 cents ... ;-)
