I have no idea if you are shooting film or digital but in either case you shot an nearly impossible shot to make in camera without a set of neutral density filters. You have three very distinctive tonal areas: the water, which is naturally darker, the middle, Mt Rainier (and from this shot it is hard to tell if it is totally snowed over) which is significantly lighter with lots of reflected light, and the sky that appears to be overcast.
In photoshop, I've changed the emphasis to reflect the three areas but admittedly, only marginally so...but really just to show the three exposure compensations you'd have to make for a more successful exposure. Just a thought. My brother lived in Friday Harbor until he passed and from his house, he had views of all three big ones: Rainier, Baker and Olympus.
