Nice! The green foreground works well and does a great job of distinguishing itself from the background. There's a nice sense of space too, love how the fog gently rolls in like mist.
If you do revisit it I would suggest working on the lighting in the water and background since it creates quite a distracting tangent with that line down the middle. Looks pretty awesome otherwise. Keep it up!
The work on the light is amazing!
Really love it!
