Please advise as to if this pond design makes sense

Here you go! A very formal (and lovely!) pond with a bog filter:

First Pond Excitement!

Hi everyone. Nearly a year has passed since I first announced here my intention to build a pond. Well, life got in the way and the project was delayed, but the day has finally arrived. My first (and only) pond will be a small, humble contemporary design with a raised bog filter. It is located...

@Lisak1 that is an awesome looking setup. Thanks for finding that. Couple of q's:
1) re: the grey pipe that is visible on the left. Does that bring water from the main pond into the bog? I saw his slotted pipe laid on the bottom of the bog so that would push the water upwards through the bog and filter it before it waterfalled back into the pond, right? If so then two questions: where is the intake for that pipe? I didn't see it in the "dry" image. Also, does the pipe have to be visible? I'm looking for a very clean, modern look. So in this case could the pipe enter from a notch cut into the top cinder block or even the interface between the two blocks (as long as it's higher than bog water level so no backflow occurs that dries bog when pump is off...)
2) also I'm looking for the top of the main pond to be flush with my flagstone (formal rectangular pieces of flagstone as opposed to natural shaped) and not higher. Is that a problem? Also, what is that step looking slab on the far side of the main pond? A step to jump into the pond?

I spoke with the patio guy and he said he was planning on using the standard liner that everyone uses and said it is EPDM (I threw out EPDM 45 and he said yes that was the thickness). I asked about which biofilter he was thinking and could we do a bog filter? He said yes we could do bog but he was thinking a biofilter with bioballs which need to be rinsed out occasionally or something like that.

Ok so progress has been made!

All that's missing is my water lily which I'm thinking of transferring to this pond and sinking into the deeper four foot section for wintering and the future hardy lotus and some goldies!!!

Ok here's an update on my pond. We have some fish now and the water is green. I've talked about this on a couple of other threads etc so I won't rehash it here. Can't wait for the water to clear and the fish to become less timid! Also the Buddha got knocked into the deep part of the pond and will be rescued this weekend
