Hiya Fabien, for scenic you've definitely chosen an image which is on theme! You have some lovely colours and to be honest, I'd probably prefer the scene to lose the sun, i.e. crop it out so we can just look at the glorious colours in the water and sky.
Good idea for Companions - again, definitely on theme. The sky is a bit neutral so I'd be tempted to convert to B&W (or retake at sunrise etc.)... could also work with a closer crop perhaps?
Watery, I agree with you completely that the fountains shot is better - personally I don't mind the T&S effect as for me it more or less works. Well taken at a very low position so well done... I'm less fussed by archive shots to be honest!
