With the overall blue cast and the softness, it does look dreamy. Good luck in the contest.

Beautiful! Are these cherry blossoms? I like the blue sky providing the back drop for these lovely flowers. It is very soft and quite appealing.

Very pretty

Very peacefull and cool. Did you do any manipulation? The white balance seems cool which works really well. Focusing on the mid-ground rather than the fore is a nice touch which also works here .. especially given the target group.
