It is very easy to want to write like Vance - his painted palaces are so beautiful. Yet they are well-constructed on strong foundations, while what is immediately obvious is the quality of the paint.
I have noticed indications that the very last thing that Vance decides in his construction of a story is the names he will give to characters and places... these are the first things that a casual reader detects and their quality is so high that in imitating Vance it is common for the writer to go no further than the attempt to conjure names of his own, to match.
Still, I have spent much effort in attempting to gain Vance's economy of expression, so who am I to criticise anyone?
Jack Vance has put a lot of thought into his work!
