In the local store i found camels, a well and beduin tent by het. I liked the theme and bought it.
(Spoiler: I didn't use any of the stuff, because i disliked the quality of the used plastic)
So i made a Well from scratch, cancelled the tent and bougt new camels and some beduin figures in scale 1:72 by Germania Figuren
The quality was so much better.
I didn't have a plan but i started anyway. Building a diorama is allways a journey for me. So I started by making a well and a fireplace and ended having a cute little oasis-scenery
