To my eye, your photo doesn't look believable because my brain EXPECTS the foreground to be darker (and yet it isn't).
What a GND does essentially is dynamic range compression - and what you'll normally want to do is compress the range into something the camera can capture in a single exposure (or the digital equivalent thereof) - but - not so much that the foreground competes against the sky.
So in the case of your example, I'd put another GND across the image to tone down the foreground so that the background is brighter, as the eye/brain would expect.
