Harbor Overlook

Welcome Deeya
Thanks for sharing your image.  The first thing I notice is that it needs more punch.  I would bump up the contrast and saturation.  The nice thing about images like this that don't include people is that you can get a little over the top with the colors without worrying about making skin tones orange and it will still look natural. 
The composition isn't perfect.  My focus is a little torn between the what is going on in the right and the left hand parts of the frame.  Let's see what the others here have to say about that since I can't come up with a solution to crop it better.  Maybe it is just my opinion and it is fine as is.
 

Hi Deeya!  Thank you for submitting you work- participation is one of the elements which keep  this board alive and useful!

The main issue I have with your maritime scene is that of composition-  there is no real center of interest.  The vessel on the right of the scene- in the fairground is darker that the other boat and that is good because that helps lead the viewers eye into the scene. Problem is, however, once the eye gets there, there is nothing but dark water and some land in the background.  If you would have shifted your angle of view so that the structure and masts of the boat in the foreground framed the boat on the far right the eye would stop wandering around looking for a main subject of interest.  The equipment at the extreme right of the scene is highlighted and becomes distracting. 

When you can't physically move your main subject into place you have to move around and find angles that place the main subject 1/3 down from the top and sides of your frame or composition.

Framing you subject in foreground elements and the 1/3 composition rule are admittedly "old school" or classical theories but nonetheless  they work in that they direct the eye to your center of interest and help you make a statement about your subject.  Framing the subject also helps add dimensionality to your images- kind of a 3-D effect that is especially useful in landscape and seascape work.

Thanks again and I hope this helps!   Ed POST AGAIN SOON!

By the way...  y'all made a mistake by giving great constructive feedback.. I'll be back with more pictures...  I really want to get better at this...

That's the idea, isn't it?
