Gradient maps are a part of Photoshop for a long, long time. It took me a while to understand how to use them for color grading, though.
Mostly because you sometimes see people overdoing it. Even in some movies, the teal and orange blockbuster look is extensively exaggerated.
The colors look just a bit flat. Besides that, the image looks fine to me.
Adding a gradient map in Photoshop using a blue to orange gradient.
With soft light and an opacity of 40%, the blue to orange tones (from dark to light colors) add a pleasing bit of warmth to the look. No further adjustments were made.
