First task at the course...

I don´t know if I´ve worked too hard with this (No, I didn´t, I just thought so when I uploaded it in CMYK instead of RGB! What a difference!), but this is the first task I´ve sent in to the course. Here´s the original. What do you think?

I´m not used to work in PS. I just shoot and post mostly...



P.S. I wonder who left the window open?




EDIT: I´ve changed the copy to an RGB of the same. I had saved it in CMYK,
don´t know how it happend, but that´s why I didn´t recognise the colours everywhere! You learn from your mistakes! I hope I will! (I´ve brightened up the cable wheel a bit too!)
