Drooled about one who impresses creatively (7)
I believe the answer is:
doodler
'one who impresses creatively' is the definition.
(person who doodles)
'drooled about' is the wordplay.
'about' indicates anagramming the letters.
'drooled' is an anagram of 'DOODLER'.
(Other definitions for doodler that I've seen before include "One draws absent-mindedly" , "One idly drawing" , "One scribbling" , "Absent-minded scribbler" , "Idle sketcher?" .)
