I believe the answer is:
drawn
This clue is a double definition.
'looking strained' is the first definition.
(I've seen this before)
'sketched' is the second definition.

(Other definitions for drawn that I've seen before include "Attracted - depicted" , "Sketched or tied" , "Portrayed" , "Sketched; pulled" , "showing signs of strain" .)
