You have done a decent job there Charlotte, great to see you are starting to give the post-pro side of things a go and see what ytou can do. You will learn more with every one you do so keep it up. Now you have a grip of the main tools, try and remember what effect each adjustment made so that you can replicate the path you took with future images. That will boost your confidence and enable you to take picture with a certain look and feel in mind.
I have had a little play and I flipped it the same as you did just for ease of comparison. I wanted to give it a brighter, summery sort of feel and am happy enough with that. Unfortunately because I cropped from a 72dpi image rather than the true original, it has made it a little posterised. I just finished it off with a little frame but that is always down to taste.
Hope you like it.
