This is hard to see it. It took me long time and I had to re see the original photo to compared them. You did put it far away. nice good idea.
Great idea, great work. Perhaps a bit subtle - one might take another look onto the themepost - but defenitely creative. One little thing to critizise: The reflection. Itīs still the one from the original image because the chute seems still going down into the water. Am I right.... - If you can change this ginalin will find it even harder to see it
....Subtle, but creative. The only thing I could suggest is the angle of the reflection. Rotate it so that it's at a downward slant.
