With the albatross, I am reminded of The Rhyme of the Ancient Mariner by Samuel Taylor Coleridge. Did you get insperation for your light placement from there?
For those who haven't heard of the story, the albatross, seen as an angel of the seas, brings wind to a stranded boat and saves them from certain death, but is in return shot by an arrow by a bored deckhand. The wind stops and they are then stranded again in a motionless stretch of water. The rest of the crew deems him guilty of dooming them so they make him wear the albatross around his neck to symbolize of the weight of his sins. As you can see from the size comparison in the picture, this are not small birds.
There's something about this particular scene which evokes on a complex scale and level more than mere concept art.
The characters & animals, even the rudimentary design of the room seems normal at first glance but the more you delve into this the more questions are created with no specific answer. Hints of associating light source of various solids (mostly Lunar amd star-based) almost ominous with its LED-like vibrant shine alongside the various Avians suggest various spiritual or cosmic symbolism, association, legend and myth.
However its familiar yet strangely alien and hard to recall anything specific even for a knowledgable viewer. That part makes this art snapshot one of the most frightening when thought altogether deeply, while still fascinatingly mysterious at same time.
I long for such to actually exist somewhere for visit, be it the alternate Earth or another country & planet. Stellar job here!
