In the Qawwali scene when Veer comes back, we see Zaara and Shabbo turning around to see him. Then when the camera comes back on them, we can see Shabbo turning around again.
When Saamiya first asks Veer to talk about his life, her hair fringe is mostly covering the side of her face. In the next shot when Veer looks at her, her hair is tucked neatly to the side.
