The main thing I see is the orange reflection cuts off too quickly. Makes it look like there's a pit in the water.

Also, think about adding a smoother transition in the sky itself. Such a small section being the only part lit up doesn't seem natural to me.

Finally, the left section seems lighter than the right section even though the light is in the middle. I know the dark parts is because of the clouds in the right side, but the sun would have more of an effect on those in that case.

Apart from those, good progress.
