4.5 is not an option ... so did you vote 4 or 5?
It would be nice if you could write why you gave the pictures the number you gave. I saw a lot of 4.5, 5.5, etc... people like comments, not just a number (half number at that!).
There is a lack of clarity to this photo and I think most of it is due to the use of excessive JPEG compression. Your file size of only 36k indicates a highly compressed image and that is what is robbing a lot of the detail and sharpness from this image. I can see obvious compression artifacts around the lighthouse. Check your compression settings when you save your file. Always adjust JPEG compression so that your file size is as large as possible, but within the challenge limit.
