Nice-a of the princesses to invite us to a picnic, g’eh, Thorigi? X3

Well no, their personalities are not perfect matches, but their designs and roles are mirrors of each other, and it’s no doubt done on purpose. Thorax (like Celestia) is the taller, brightly colored sibling who’s more reserved and diplomatic, while Pharynx (like Luna) is the darker-colored, shorter sibling with a more grey personality. Thorax is known for his kindness and benevolence towards his subjects, like Celestia, and while it’s true Pharynx never wanted to be evil for the sake of being evil like Luna was as Nightmare Moon, Pharynx and Luna were both outcasts prior to gaining/regaining their throne. Look at ‘To Change a Changeling’ and ‘Luna Eclipsed’ from S2 - both are about the grey personality sibling being an outcast and, by the end, becoming accepted.
 
Honestly I think one of the biggest differences is actually just age. Pharynx is the older sibling to Thorax, while Luna is the younger sibling to Celestia.

I think it’s not that solid, like how Pharynx never wanted to lead or turned evil.

I agree, but I don’t think that it was a very subtle comparison. It’s fairly obvious and intentional.

I have to comment on this: Does anyone see the similarities with Thorax and Phanrnx, and comparing it with Celestia and Luna?
 
I really can see it, especially with how they are now: Thorax can be the parallel to Celestia, while Pharnyx’s story really reminds me of Luna, especially when she actually meets the Ponies for the first time since she was release from her prison on the Moon…

Love Pharynx’s expression.
