Thailand has so many type of markets, for example, outdoor market for whole sale and cheap stuff, sunday market (mostly selling food), and night market. I have been searching on the Thai sunday market that we will be using for the scene that Aranya and Zombat met.
I also include the accessory booth. The handmade hair pins usually sell on the floor (hair pins that made by college students). The accessory that sells in proper booth, mostly they are more expensive due to the rental.
I hope you would find this reference useful to your drawing >.<
