First of all, I cut the red balloon and liquified the ears to make them look like hearts
step 2 of 5
I used the part of the picture on the left as an overlay for the heart to give it a bit more structure.
Layerstyle is set to overlay with 85%.
Besides that I also used a part of the balloon to fill the visible part of the heart.
step 3 of 5
I made the structure of the hand with a part from the window.
I selected every finger individually, placed the window above it and set the layerstyle to overlay with 41%
step 4 of 5
After that I combined the balloons with the rope and the heart and copied this twice.
I also made a new structure for the heart on the left side, so they don't look all similar.
The left heart has gaussian blur with the amount of 1,7 and the heart in the middle with the amount of 2,8
step 5 of 5
I didn't liked the overall colour, so I used the fotofilter with yellow and concentration of 65.
After that I copied this layer, used gaussian blur with the amount of 1,7.
The last step: Layerstyle of this new layer set to overlay and opacity to 18%
