Two attempts at the Ocean chapter of the Sessions: Macro course.
The first attempt came out a bit more "stylised" than "realism", and this may have been due to choosing a night scene of the river Thames.
Attempt 2 was a more grounded attempt to convey realism, however it wasn't until after rendering and compositing did I notice that the time of day the scene depicts could be interpreted as both first, and last light of day.
