So i grabbed the 2007 Ford F350 Ambulance i created in Blender.
And decided to put together an ER hospital scene.
Luckily my experience working in Hospital gave fruition to this scene.
Currently it is not animatable, But it can easily be rigged for animation.
Used some textures from Polyhaven.com and other edited in photoshop.
Finally rendered using Blender's Cycles render engine and Post composited in Blender
