While I feel as if this round was more competitive than it necessarily looked at first glance because of your color choice going against the specific wording of the category, at the same time, I feel as if picking green for a ship does fit the spirit of the category. That, combined with your original build and the overall atheistic of your build which I absolutely <3 wins the day for you. From an artistic perspective your colors are boss, and all the components really come together to make a mystical scene. I can almost taste the saltwater just looking at your build. ^^ Thus, you have my vote- congrats on moving on! ^^
Completely different from what I expected to see from the category, but I'm impressed how you managed to make it look realistic despite the color choices. I feel like you could have made it more fantastical to better fit the category, but you still get my vote.
