Thanks big time, Vokaris, perhaps this thread can be put in the Tutorials section. To good to get lost.
I do have a little question though.
"When we make photoshops and they are not meant to be Photorealistic chops
- Do we still need to follow these guidelines as strickt as you shown them here?"
I am asking this, because - in your gif it seems like - if you just keep your lines moving outward, even under water, you can never go wrong with a reflection. And some of the images show scewed buildings in the water and straight buildings above the water, this probably because the water is closer to the camera then the original building.
If you look at this photo I took one winter, you can even see much more in the water (ice) then you can see above it. Look at the man standing on the machine in front of the building.
Personally I would only use a small section of the bottom of a building and take that as a reflection in the water, continuing the line from above the water under water, leaving the rest out, as if the water is not that smooth to begin with. This way you hint at it, without giving people much to be bothered about.
