I think that I shall never see,
a sight as lovely as as tree....
The problem is I've seen it a thousand times in every beginning photographer's portfolio. So the problem here isn't that it isn't a good foggy day tree shot, but rather its not any new interpretation that warrants more than cursory glance and sets it apart.
Think about the "sentinel" title you gave it and what is seen in the photo. What is the tree protecting? Is it seen in the photo in the foreground or background? Looks more like Papa with the twins in tow, with the third sibling looking suspiciously different, like it was adopted or mom went nuts with the mailman...
Compositionally lining elements up like ducks in a row sends the viewer on a one way trip from the object which contrasts the most in tone, size, color, sharpness off into infinity. That's far less interesting that a photo where the elements are arranged in a triangle or other odd number of focal points around the frame that will tend to pull the eye around the photo in a circle back to the strongest focal point on a different path. The problem with linear paths is that even if the viewer does go back for a second look at the more compelling center of interest they wind up backtracking over things they've already seen. That's redundant and boring...
See the edit I did on this photo which had the same "duck in a row" composition of elements in the original..
Photos with something large in the foreground like that one grab attention more. So for example of you had the large tree in the foreground with the smaller ones and a house it provides shade to seen directly behind it the Sentinel title would make more sense and all the elements in the photo would be more unified. The viewer would be pulled into the center core of the photo not invited to exit, stage right ---- >>>>>> by the ducks in a row.
That's not to say the "ducks in a row" alignment never works, but there needs to be something interesting at the end of the eye path to reward the viewer for following the ducks.
