This is the way I see gloom, faith and light. I want represent the transition from "gloom" to "light" going through "faith", the progression from despair and desolation
to salvation and illumination which can only occur through hope and faith.
The way to browse through is ideally to start from the first picture in the Gloom section, going all the way to the last one, in order, without skipping any. This should make sure that the Gloom reach its crescendo, with the last picture being the gloomest.
Then you can move to the Faith section, and the same applies here. You will need to view all the pictures from the first one to the last one.
Eventually you make your way to the Light which is meant to be a sort of relief and reward after you've been through Gloom and Faith.
