I point up after drone is lowered (10)

'lowered' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?

'i point up after drone' is the wordplay.
'point' becomes 'detail' (synonyms).
'up' says the letters should be written backwards (in down clue: letters go upwards).
'after' means one lot of letters go next to another.
'drone' becomes 'hum' (drone can mean to make a humming sound).
'detail' in reverse letter order is 'liated'.
'i'+'liated'='iliated'
'iliated' after 'hum' is 'HUMILIATED'.

'is' acts as a link.
