Very cool! The SBS helped me to see how smartly you used the source! Nice!

nice usage of the source...GL author

This made me laugh. Try duplicating the middle dog figure and flipping it and lowering the opacity on 'multiply' mode...this will give you a reflection that I think you might need.

if i understand you ,, thats what i dit but the source image have his own shadow

Try to blend your reflection with the source's reflection by using lower opacity in your reflection layer. Also with a soft brush with low opacity you can erase parts of your reflection for a better result.

I love the work you put into this! Drawback, reflection in pond is wrong, like the DOF!
