Not that this image looks very real anyway, but what is the main reason that these baloons don't belong? Notice that there is no reflections! Of course those baloons would make a reflection in the water if there were really there. This is a good example of what can be done with composite images to manipulate reality, but it is even a better example of what not to do in terms of reflections and shadows. Notice that the shadows on the baloons are on different sides.
- Use the quick selection tool to select all the sky and trees around the baloon

- Select > Inverse (to select the baloon)

- Open your lake image
- Paste your baloon using Edit > Paste
- Click the move tool
- Rescale your baloon to fit the image by dragging the corners of the bounding box
- Duplicate object (drag layer into new layer button)
- image > rotate > Flip layer vertically
- Move into place (mirror image)

- Filter > Brush strokes > Sprayed Strokes
- Filter > Blur > Motion Blur

Defringe your images
Sometimes you may have halo of fringe pixels around your image that makes it look unreal. You can easily eliminate them by using the method below. This works best when you have used the quick selection tool or magic wand tool.
- Copy and paste a selection into a new or existing layer.
- Choose Enhance > Adjust Color > Defringe Layer.
- In the Defringe dialog box, type the number of pixels you'd like to replace around the object. A value of 1 or 2 should be sufficient.
- Click OK.
