Drew on being this overcome by awe? (12)
I believe the answer is:
wonderstruck
'drew on being' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'overcome by awe?' is the wordplay.
'overcome' becomes 'struck' (I can't justify this - if you can you should give a lot more credence to this answer).
'by' is a charade indicator (letters next to each other).
'awe?' becomes 'wonder' (awe is a kind of wonder).
'struck' after 'wonder' is 'WONDERSTRUCK'.
'this' acts as a link.
Can you help me to learn more?
(Another definition for wonderstruck that I've seen is " Astounded".)
