I’m thinking of removing the boat… Might change later.
Without boat:
The boat is a nice twist, I should have keep it.
Maybe a bit more in scale with the rest.
If you like your outcome of the challenge, then continue adding more.
Repeating the things you’ve learned. Sharpen your skills.
HAve fun!
Perhaps make a jetty for the boat to be tied up to?
Check scales of each item with a theoretical human sized block. A boat about half the height of a lighthouse? it does not look glaringly wrong but just some parameter to keep in mind making scenes.
I like the boat too, neat idea, but I didn’t even see it until I read the text above the image, probably because this is a (purposefully) dark scene. Maybe consider moving the boat into the foreground so it stands out a bit more against the shadows of the rocks. That would bring a bit more depth to the scene as it is =)
