Thanks a lot for your replies and suggestions!
Your interest is very valuable.
You are completely right about post production and HDR issues, since I'm not very good and skilled in that.
I'm not a professional photographer and I need to improve my images quality, I see..
Anyway, regarding the white balance, I know it's not such natural but I chose a warmer look on purpose.
And I used a short song to have a lighter file inside the project.
Would a bigger file affect the loading time of the music?
Well, if you check again, some graphic and functions have changed.
