Thanks Alvordr. Yes, the lighting is not perfect, probably. But I need to forget this one for a while
in order to see it with new eyes.
About the light on the hallway: I wanted to add a light source outside the camera view field.
Someone is coming, men in armour holding torches? That's a part of the theme.
This dragon is obviously facing someone and is about to defend his treasure.
That's why I have a slightly warm color in the front of the scene.
Yes, there's probably something odd about the head lighting. It is not a hundred percent realistic.
I understand that too, but I don't know how to fix it. I probably need more practice.
I'll see what I can do about that in the next trials.
