Blame screen for distorting likeness (11)
I believe the answer is:
resemblance
'likeness' is the definition.
(I know that resemblance is a type of likeness)
'blame screen for distorting' is the wordplay.
'for distorting' indicates anagramming the letters.
'blame'+'screen'='blamescreen'
'blamescreen' anagrammed gives 'RESEMBLANCE'.
(Other definitions for resemblance that I've seen before include "Similarity of appearance" , "Likeness" , "Similar image" .)
