Hey Robyn, yes that was my world settings. Note that the HDR is in an Environment texture, not an Image Texture, otherwise it won't map properly. And also the images should either be equirectangular or a mirror ball:

 

 You should get a complete 360º angle of the image when you look around the scene in the rendered view sort of like street view in google maps. You change it in the Environment Texture:

 

 Let me know if you want the composite settings. It's actually simple to get the object to look like it's in the real world.
