Fountain Hunting

I'm looking online for fountain inspirations. I want to DIY this project since everything I like is at least $500, and I'm not really loving anything.

Initial thoughts are that given the space it needs to be square. I'd like to hear the water fall and I'd like to see a stream or a cascade of water. But the sound can't be too much as it'll be next to our bedroom. Not sure if I like stone vs pots yet. Then I realized I could add night time lighting accents.....ugh,more to think about!

Here's what's catching my eye:

I love the cascading water feature. Don't super dig the pots.

Should I have the water fall from up high?
I like the squareness of it all. Should I make it bigger and have fish?

Round might work.

Square, I like, but having a pour like this might be too loud. And its a little too square. Too museumish not enough home vibe.

I like the pool on top.

I like the stone but wonder if there would not be much sound.
Everything is a little off and not quite right but almost there.
