The chain texture connecting the lantern to the lantern bracket does not visually connect. If possible I would like to suggest that this be fixed since it can make the lantern look as though it is floating from certain angles and when you are further away.
There are three screenshots below to show how a Hanging Lantern and Wall Lantern currently look as well as a quick cut and paste of what the two of them would look like together so that the chain is visually consistent.
