Not too shabbay, I cant spot any obvious flaws side from the edges are a lil jerky, it might be that anti-aliasing turned off or jpeg settings but again easy to fix.
The water is still so the reflections will be still, ya easily get away without manipulating it.
the sky has no stars, thats the only lil thing but they are easy to put in.
Put some twinkling stars in the sky maybe a cloud and bam S rank
But its still pretty up there in the high score region about an A
You should be able to animate the crane arm swinging and clouds moving slowly and stars twinkling to get that ever so hard to reach S+
god forbid
