newbie here, I am finding this fascinating. I have never worked with "eye rhymes" or non-illustrated minors but I will have a go.
Initially I couldn't "see" anything then I stood back from the images and looked at them from the other side of the room to give me a different perspective.lol
the first word that came to mind was symmetry. The 7 of pents is not symmetrical, the 4 of cups is, the 3 swords (despite being an odd number) is symmetrical in its imagery.
I see one coin on 7 pents being the odd one out, like there is a disharmony. the vines are winding round, also not symmetrical so something is binding this disharmony together like the situation fells like it is being bound up or "strangled".
In the 4 cups there is the symmetry of the cups, the vines are still not symmetrical but are diminished in number after the 7 of pents. I see this as meaning the constraints of the 7 of pents are being diminished and there is movement towards harmony/balance with an agreement of sorts due to the emotional aspect of the cups.
Moving to the 3 swords bringing symmetry. the vines are released and the swords are "free" from the contraints. I see this as being something that is stable and balanced, yet it looks like one tiny movement either way and the symmetry/balance is lost, the sword in the centre feels like a middle ground has been acheived with 2 sides equal.
what has just come into mind bizarrely is an image of a child learning to ride a bike for the first time without stabilisers. The odd number in the coins is like the child desperate to do it on their own. mum and dad (the restricting, sometimes overprotective, vines) finally trusts the child (cups) and lets go of the bike and the child has to maintain the stability with the watchful eye of both parents on either side, they have acheived it but could topple over and hurt themselves if they don't concentrate.
I have probably contradicted myself at some point as I have simply typed what was running through my head as I was thinking it
