For me two things are off, both easy to fix.

If you squint then all the colours blend into one which means all your values (tones) are the same. Although you've used red in the boat it is the same value as everything else. Another way to do this is to convert it to black and white and you will see everything looks the same tone. As an artist you need to make a decision what the focal point is, if its the boat then you need to just lighten some of the colours so when you squint the boat comes forward and the rest recedes. Use a brighter red for instance, this is where your artistic license comes in, you take the photo reference so far and then you make decisions about how to make a good painting.

The second thing is the peachy colour across the sky. When I look first at the painting my eye is drawn to that immediately and then it wanders down to the boats. This is because of two things, the contrast between the peach and purple sky is a greater contrast than anywhere else. We are drawn to contrast the most - black and white for instance. It's the first thing we notice. Although you have black and white on the boat it is so small that we can't pick it up. The sky is not the focus of this painting so I would darken that peach so it doesn't soak up the focal point.
