I don't know - I think the colours convey the situation well - in shade or after the warmth has left the light during dusk). I certainly recognize the time and feeling of what is being conveyed here, though I am hopefully close to camp or cooking over a fire during this time!
But I also used to shoot a lot of uncorrected daylight balanced film, so I usually leave my WB to 'daylight' and only change in case of severe artificial light or cast - usually when people are in the frame.
If you do warm it up, I think only a small increment is needed. It's a nice 'sense of place' shot.
