To me it appears unfinished. I dont prefer a gloss finish, but a semi-gloss. That is all personal preference however, whatever you like is the right finish.I would opt for danish oil, topped with deft semigloss. I did take a closer look at grain direction. Where you screwed up is that you should have said you CAREFULLY placed the pattern to get the most out of the grain direction

. When looking at it magnified though, it almost looks like some vertical scratches or machining marks in the hind 2/3rds of the fish.It could just be in the photo though.
