Hello @PresumptivePanda
I am really glad you like my work! Thank you so much for super kind words!
The biggest challenge would be probably the water (although there were multiple other ones too haha). I used simple Single Layer Water shader which is super handy, easy to use and produces really nice and convincing results, but for some reason it receives hard and sharp shadows from other objects on its surface, even when light is fairly diffused.
I found workaround it by editing INI file and was able to blur shadows to make them more realistic
