You could bring that polemic kind of criticism against any chess set. The pawns in the Dubrovnik set look like Jabba the Hut, the Dubrovnik bishop looks like a child wearing a bobble cap, the queen looks like some vandals broke off the crown, 1850 Staunton knights look like they have weight management issues, soviet knights generally look like the monster of Loch Ness, the Reykjavik rook looks like someone put up billboards on top, etc. Easy to come up with that kind of stuff.
And the reason why Fide doesn't use the World Championship set somewhere else might be .. because it's the World Championship set?
So Fide claim that this set is Greek inspired?...
King- Looks like a Dubrovnik queen
Queen- Looks like a Dubrovnik king
Bishop- A BCC bishop after being hit on the knop with a frying pan
Knight- Romanian knight carved with an ice cream scoop
Rook- Poor mans Chavet
Pawn-
So essentially a hodgepodge of many different styles rolled into one.
