If it's a real couple, they are a little small comparing to the window and the door, and where are their feet?

Ooops. I had another view of the image. Thanks! I edited it. I hope this time the size is ok.

Ah... a silhouette... romantic!

Another suggestion: try to see an actual silhouette like that behind a window glass... Maybe it needs a little bit of blur and less opacity.

It doesn't look romantic :S , Looks like she has him against the wall and is threatning to thump him. Perhaps use lanters instead of candles, the flames look orange,

@Barnacle,damn man u are right looks like some naughty game,but for some people maybe is this romantic...@author...nice work,,,try to use real candles this look a bit unnatural...good luck
