There are only five places to role play in the Sand village and is very small compared to the Leaf. Since the village will be hopefully increasing I think it would be wise to increase the topics to a more reasonable amount.
My Ideas as a Jounin of the village:
1. Sparring
2. Official Hospital
3. Kazekage Mountain
4. Training Area
5. Dessert Outskirts
6. Kazekages Sanctum
7. Border of Otagakure ( Sunakagure and Otagakure were once allies and I think meeting grounds were present at that time)
8. Chuunin Exam Stadium
9. Black Dessert
10. Lizard Stand
11. Underground Meetings
12. Housing Area
13. Prison
14. Library
15. Sands Graveyard
These are just some ideas I came up with but yeah I think the Sand Village needs more locations.
