fantasia

I'm a little stuck... Click here to teach me more about this clue!

'arty composition' is the definition.
'fantasia' can be an answer for 'composition' (fantasia is a kind of composition). I'm not certain of the 'arty' bit.

'admirer it's a refined article' is the wordplay.
'admirer' becomes 'fan' (fan is a kind of admirer).
'refined' indicates anagramming the letters.
'article' becomes 'a' (the indefinite article in English).
'its'+'a'='itsa'
'itsa' anagrammed gives 'tasi'.
'fan'+'tasi'+'a'='FANTASIA'

'from' acts as a link.
