Where the wall and floor meet

I'm trying to make it appear as though the artwork of the duck is on a wall and in front of the other two ducks. How would I make a line across to look as though the floor and wall are meeting? Or is there another way?

Like this? YOu could even get fancy and add a reflection of the upper duck into the floor.

This was kinda fun... Not sure if this was the best way to execute it. However, I added a little gray shadow on the floor and a little bevel and emboss to give the "picture" a little 3 dimensional look..

Similar to Kirk's approach I guess. Added a new layer, drew a gradient from the "floor/wall interface" towards the ducks, masked out the wall, blurred the gradient layer a bit then adjusted opacity to suit [only 10% opacity]:

Thanks! I'm liking this one the best. How far towards the ducks did you draw the gradient line? Can you explain how you mask out the wall and blurred the gradient layer? Other than the basics (levels and curves) my Photoshop knowledge is limited.

Well I probably drew the gradient from where I wanted the "floor" to start down to around the ducks' necks, using black of course.

I then added a layer mask to this gradient level.

Next I briefly made this level not visible [click on the eye icon next to it] and used the rectangular marquee tool to drag out a selection over the "wall" I wanted. I then clicked on the gradient layer mask and filled the selection with white before making the gradient layer visible again.

Still with the gradient layer selected I added gaussian blur [In the filters menu] with a radius of 2.0 before finally bringing the opacity of the layer down to taste [around 10 I reckon].

Thanks again everyone!
I've been working away at this and have it almost to my liking. How do I go about selecting just the 'artwork' on the wall and adding a bevel/emboss to it. I know where to find the blending options but I'm not sure how to get the 'artwork' on it's on layer. Sorry for the novice questions.

So I was a lil bored tonight, lol ... here ya go

That's weird, when I look at this post and my website at work I can't see the line going across. But when I look at it on my monitor at home I can.

I barely see a faint line going through the middle of the bigger ducky's head - is this where the gradient begins?

Kind of fun...

Yes, except on my monitor at home it is easily noticeable. Here at work I only see white. I guess I'll have to make it darker.
