It depends what feel you are going for.
The left your hair looks blonde (due to lighting) and fun (curly)
The colors in that photo are more pastel.
The right you look like a red head and the colors pop out more.
Both photos are good.

The one on the left looks better, the one on the right is more real, ur better off using that on dating sites so people don't meet you and think wtf.
