You're welcome, Rhyldur.
It looks very structurally sound as is, but I think what it may be missing is intentional lighting. The image has an overcast feel to it where it's mostly evenly lit. Maybe use this image as a base and try different lighting scenarios. I've seen a few times when people took the same image/scene and repainted it in various situations (e.g. sunrise, midday, stormy, golden hour, night, snowy, etc.). I've not tried it myself yet, but I imagine it would be fantastic practice.
Have you used much reference? It'll help you know how to light the various elements of the scene and provide a lot of information you may not otherwise think of, like the light reflecting off the water onto the underside of the boat and the subtle changes in colour temperature in the shadows, etc.
You could also practice creating thumbnail composition studies to try out different 3 or 4-tone studies of what kind of light and colour structures you want the piece to have before committing to a whole painting.
If you've not taken it yet, I'd highly recommend Nathan Fowkes' Pictorial Composition course on Schoolism -- I found it to be tremendously enlightening in gaining a good understanding of composition. I had to rush through the course due to some time constraints, but I feel I grew a ton as an artist trying to do the exercises as I had time and doing my best to soak in the instruction. I'd say what he teaches is gold for any artist willing to apply himself.
Here's a piece of a viking ship by Justin Sweet I saw a while back. It's gorgeous! There's so much going on -- from atmosphere, to colour and light design structure, to beautiful lighting in the water; I'm nowhere near this level of skill, but it's really inspiring.
I hope you're feeling better.
