Atlas drawn roughly by learner with shortcomings revealed (5-3-3)

I believe the answer is:

warts-and-all

'with shortcomings revealed' is the definition.
(as in a warts-and-all biography)

'atlas drawn roughly by learner' is the wordplay.
'roughly' is an anagram indicator.
'by' means one lot of letters go next to another.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'atlas'+'drawn'='atlasdrawn'
'atlasdrawn' anagrammed gives 'wartsandal'.
'wartsandal'+'l'='WARTS-AND-ALL'

I've seen this clue in The Times.
