I find your image beautiful. The colors are great and the silhouettes and composition is awesome. There are some tips when you scan an image than can help you improve them when posting them.
1) The horizon looks a little tilted. You can correct this with any photo editing software, e.g: Photoshop. In PS you can simply rotate the image till you get the desired position, or you can draw a line that follows the horizon on the photo, meaçasure the angle of the line, and that angle is the one you should rotate the image to get a perfect straight horizon.
2) It?s difficult to appreciate this great photo with all those little white spots that are just little dust on the negative or dust on the printed photo at the momento of the scan. To improve this in Photoshop you can use a tool named "clone stamp". With this tool you can select a pattern from the picture that you will clone on any other place you need it, in this case that place would be those white spots. To select the pattern you use Alt + a mouse clic, and after that you just have to paint with the "cloned" pattern the area that needs it.
3) More sharpness and a little "levels" (this is something like adjusting the shadows, lights, or in other words, brightness and contrast) adjustments in Photoshop could improve your image a lot.
All this is not "manipulating" your image but digitallizing it properly. All scanned images need a little work to make them look like in printed paper. I hope you get the interest on this and discover the great advantages of this kind of software.
I attach a sample file to show you a what i?m talking about. It?s not the best it could be done, but simply an example of what can be done. Things look much better when you work directly with the original scanned file, that?s much larger than this one.
My best regards, the picture and the place are just beautiful!!
