Connie, When you convert your image using the grayscale it tends to give a flat mid-tone image that has to be adjusted,usually with the contrast.
Or you can go to Grayscale Mix-
Grayscale Mix is found below the “Basic” and “Tone Curve” views. Click the “Grayscale” button next to the “HSL” and “Color” buttons. This converts the image into grayscale tones, but allows you to adjust each color tone individually. Play around with these adjustments until the tones are most balanced and artistic
Or you can use the Slit tone method-
Beneath the “Grayscale Mix” views is the “Split Toning” option. This type of conversion is one of the most involved. Adjust the slider to set your highlight color and saturation level, and then do the same with your shadows. From here, adjust the balance of which is more prevalent, highlights or shadows. You will find that at this point, your image is not in black and white, it is in whichever colors you have chosen as your shadows and highlights. From here, you will need to go back to the “Basic” option. Here you will adjust the vibrancy and saturation of the overall image. As you adjust these sliders, your image will become black and white with prevalent tones from your split toning.Hope that helps.
Onto your image, I like the overall look but find it just a bit busy. I might also clone out the stick in the water on the right. For me the horizon line is cutting thru the entire image. I do like the clouds and the conversion looks good.
