I looked at your rack above as well as your update (by clicking the link of the picture). You've put in some more work.
The first thing that draws my attention is the QPAS filter. It's a niche stereo filter. There's noting wrong with the QPAS, put apart from the "Outs," there's nothing else in your rack that really supports a stereo signal. I'd want something like a Joranalogue Filter 8 or an Intellijel Morgasmatron if I was putting together a first rack and add the QPAS later when my system could support it.
You talk of "space/ocean" styles of sounds. That makes me think of reverbs with long decay times and delays with a lot of feedback. I don't see any modules of those types in the rack. Eurorack effects that are designed to be modulated are awesome. There are other options with outboard gear like pedals... it's going to depend on your needs.
Also missing are any dedicated utility modules. The Maths can do some of that work as far as attenuating and attenuverting signals. But if its doing that duty, you might not be able to use it for something else.
Some other bits you may want to add would be some sort of noise source (pink and white). Noise can add a bit of character to a sound, especially when mixed and filtered with that sound. Sample & Hold as well as a logic module will give you some additional possibilities... but only you can say if that would fit your needs.
The Zadar is good. But it might not be bad to have a couple of traditional ADSRs as well. I'd go with an ADSR with lots of CV inputs like a TipTop Z4000 and have one or two of them in the rack.
For your set-up, I'd have one mixer that's capable of audio and CV mixing (the Mixup should do this) but I'd also have a main mixer with even more channels. I have a Blue Lantern Stereo Sir-Mix-A-Lot. it has six inputs plus two stereo returns. It was in the $200-$300 price range. That might be the ticket since you'll probably be adding more modules and possibly effects. It would also be great pairing it with the QPAS.

Thanks so much for the input really really appreciate it. I’m gonna do a lot more homework and I’ll post an update soon thanks!
