Way too much "sexy" going on here. You're missing a large amount of the boring stuff that serves to make all of that expensive, snazzy crap do what it should. Yes, there's definitely a lack of modulation sources, but without more VCAs, attenuators, mixers, and other stuff that has sleepy panel graphics and a lack of blinkenlichts und twistenknobs, you've got a MUCH bigger issue building here than simply dropping a few more EGs in will fix.
Starting with the above, and prior to adding anything, remove as much as you possibly can (and be brutal!) while maintaining the sort of base functionality you're aiming for. My bet is that about half of what's there will go away in this process. Then, go back in and double only certain modules when that doubling will contribute to the sound of a single patch. Doubling VCOs for detuning, for example. Next, if the idea here is to have a second voice-path, add that back in...but again, be as simplistic as you can, just like the above.
At this point, there should be a lot more open space. Now...start chucking in the "boring" stuff. The result won't look as dazzly as the above...but it will work far better than where your above build is heading.
But before doing ANY of that...go and check some tutorials on how synthesis methods work. Seriously...because you have 4 oscillators (but not...exactly), you don't have to have 3 VCFs. You'll get a LOT more punch out of taking all four and mixing them, then feeding that through ONE filter. This is one example; there are others present here, and one of the worst ideas I can think of is plunging into a $10k swimming pool without reading the manual to find out how to put the water in first. And modular synthesis can easily become that...OR WORSE.

thanks Lugia for your reply.
can I ask you if you could provide me with some specific module that you will add (I'm thinking about what you said, " VCAs, attenuators, mixers, and other stuff that has sleepy panel...") so I'll look them out and study more.
About modulation, what do u think about Tides (2018) and Quadrax?
