If you wish to watch at the original sized pictures, just click on them!)
this is the original picture (I highlighted details which I removed)
this is the edited picture
here is the process of editing:
1. I removed and improved some details(round with red on the first picture) using Clone Tool
2. I cut the man from another picture and transfered on mine using Magic Wand Mask Tool and Brush Mask Tool
3. I inserted the picture(you see the poster in the left high corner), which I resized first of all, made it smaller.
4. I adjusted saturation, lightness and brightness a bit to make picture more saturated.
