Looking at the rusty gate the other day, I was reminded of Judy commenting that it looked like ancient cathedrals and the alcoves and niches where icons or perhaps candles burned.
The row of vague triangle shapes along the top of the gate started to look like flames.
Those certainly belong in alcoves.
So I have taken the large dome shapes from elsewhere in the gate,
reduced them and drawn them over the flames.
Flickering in the gloom of an ancient place of worship.
