Images Taken on an Older Camera

The photo was taken with my first DSLR, a Nikos D3200. I now shoot with a Fujifilm XT-20. The location is Diakofti, Kythera, Greece. It is my first "decent" long-exposure photo. The main challenges were to get to the location before sunrise and find the appropriate settings before shooting the photo.
If I remember well, the editing was done in DXO Photolab, and apart from the basic setting, I had to darken the sky.
