This is my first try on making a dreamy-look wallpaper....Tell me what you think as I want to improve myself in Photoshop!
Nice Job on the image, looks very good for a first try, and welcome to FriHost by the way.
The only issue is that the area above the man and woman (the white area) draws away from the white lady in the white dress (kinda camouflages her). You may want to darken that area or make it be more transparent and show more water so the people stand out more, similar the lady in the yellow-green shirt.
Nice image still, good job.
EDIT: I voted and gave it a four!
