Glad you thought my comment to be of some use.
Regarding the use of Photoshop.............There is one thing that you will come to appreciate as your hobby progresses and that is that software (not necessarily Photoshop....there are many simple free programs available) is a useful tool and in no way should you consider it as cheating or changing a picture into something it was not.
Most jpg images can benefit from a little "sharpening" as many cameras tend towards producing slightly soft images.
"Cropping" is a useful tool for fine tuning your composition........sometimes you do not see something which detracts from your in camera view (as in the case with the mod I posted) also you may decide that what you originally intended when you took the shot does not quite work when you get it on screen.
Auto "White Balance" on your camera is usually quite accurate but night shots can easily confuse the camera and the final shot ends up not how you saw it in real time. Slight adjustments can improve an image.
"Levels" is a great tool to ensure that the contrast of an image is improved and you will learn to check the histogram of your pictures to ensure accurate exposure.
"Cloning" can be essential to eliminate features which you cannot avoid no matter where you stand to compose your shot. As a hypothetical case..........what if you picture above had discarded litter in the foreground that you could not move out of the way?...Your final image would be true to life but not very attractive.
I could go on and on...........My conclusion is that software is a valuable aid to getting the best from your pictures and should not be dismissed in any way. It will not recover a bad photograph but it will get the very best out of good ones.
Always try to get the picture right in the camera but do not join the league of so called "purists" who consider any such tuning as being taboo. After all your camera adds many software tweaks to produce the image in the first place....all you are doing with software is controlling the final outcome.
Also you may find you like the effects that can be produced from your camera shot..........I quite like converting some shots into an artistic "painting" effect. There are many photographers on here who use software to create some incredible surreal images.
As for this specific picture........apart from my "crop" I would perhaps add a very small amount of "sharpening" (always use "unsharp mask" (sounds odd I know)) but this used sparingly give a better effect than some of the other tools
