Person skilful in a version of some art (7)
I believe the answer is:
maestro
'person' is the definition.
(maestro is a kind of person)
'of some art' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'some'+'art'='someart'
'someart' with letters rearranged gives 'MAESTRO'.
'skilful in a version' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for maestro that I've seen before include "special performer" , "Master of an art, or a great conductor of music" , "Noted conductor" , "great expert" , "Master of any art, from Italian" .)
