I’m starting study Blender with simple models
Those are lovely textures This is amazing work, especially for a first render!
Have you tried putting a night HDRI in for lighting? The emission of the lanterns and flowers is turned up very high, but you can’t see anything else in the background, because the light from those emissive objects is not affecting anything else. If you were to add slightly more background light and turn down the emission slightly, it would appear more realistic. Your lanterns are vivid and lovely, just perhaps slightly too vivid. A small fire, or even electric light, would not create that quantity of light.
No, I didn’t use HDRI for it. Thank you very much for your advice, I’ll try!
