The overall lighting is simply “too dark.”
You need to start by illuminating the scene, such that a histogram of the image is mostly-centered. You want details in the shadows without blowing-out the whites. Believe it or not, the much-maligned “ambient light” is (imho) quite good for this.
Remember that your lights don’t have to be white, and probably should not be. The overall-lights set the basic feel or mood of the scene.
Once you’ve gotten that down, you start injecting highlights, which might be very small spots. Some of the things you want to consider in this step are: - Defining the edges of objects, such as with rim-lights. - Defining the character of a surface. - Providing complementary light-colors to balance the color of the object itself, and to avoid “color bleed” (important for printing), or “color jump” illusions that can happen when, say, blue and red are adjacent to one another. - Varying the saturation and hue of the colors in the scene.
If you want to achieve “mood,” such as particular shadows, always remember that what your eye really sees is contrast. Look at a “black” spot on your monitor, then turn the monitor off: soon you see that the screen really is, and always has been, “simply grey.” That opaque-black that you see isn’t really there, except that it is adjacent to a much brighter spot and it has a sharp brightness-transition vis a vis that area, so it appears “black.”
All of the colors in this scene, except maybe the banana, are richly saturated. So are all of the lights used to illuminate it. Experiment in these areas…
Note: If this is the mood you were shooting for … sort of an “old masters” look … then feel free to completely ignore all of the foregoing!
