You still lean on translation
You can sound out a couplet, but to truly read Ghalib unaided, with all its compression and shock, you need a higher level.
You can't yet hear the music
Metre (bahr), rhyme (qafia), refrain (radif): you sense them, but you don't yet feel the architecture that makes a ghazal sing.
The wordplay still hides from you
When a word means both "wound" and "flower," the couplet works on two levels. Catching that needs advanced vocabulary and instinct.
You're close to the tradition, not inside it
500 years of ghazals, nazms, marsiyas. You've stepped in. Now you want to read it fluently, the way the tradition is meant to be read.
