Criticism most significant, dismissing one crude drawing (8)

I believe the answer is:

stickman

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

'crude drawing' is the definition.
I know nothing about this answer so I can't judge whether this works.

'criticism most significant dismissing one' is the wordplay.
'criticism' becomes 'stick' (as in giving someone stick).
'most significant' becomes 'main' (I've seen this in another clue).
'dismissing' suggests deleting specific letters.
'one' becomes 'i' (Roman numeral).
'main' with 'i' taken out is 'man'.
'stick'+'man'='STICKMAN'

Can you help me to learn more?
