As usual, Sai was sitting under a tree with a notebook in his hands, drawing nothing in particular, just using his surroundings for inspiration. He doesn't seem to know what to draw yet

as Sai went blank into his thoughts he's still thinking of something to draw

Sai: talking to himself "Hm.. How interesting... I don't know what to draw today."

he just keeps staying under the tree with the note book in his hands and the pen with ink in his other hand
