To be honest, the original world I created had three moons. But I decided to change that in the VN so I can use the standard dome used as skies that some very nice modders put at the disposal of guys like me who are not the best at creating assets. And it saves time. Compromises.
I think I will go towards more of the "Hollywood night", the blue filter, probably still a little darker than the actual movies though where it is nearly as bright as day. But yeah, I was having a look at the game itself and it's true that some of the renders are too dark. Perhaps have the MC use his light spell a little more often too...when it makes sense story-wise at least.
It's just...lighting is the hardest part of making renders, ask any dev. I am starting to get better at it, but it's my first game and I have no background in photography or things like that. I do learn about it though, look into some tutorials, it should improve in the future.
And I appreciate your comment on the lore and the story, thank you very much.
