This whole project is great! And as others have said, the models that you've chosen really channel the "actually rank-able" vibe of the high elves from early 4th edition WFB. Great work and thanks for sharing!
As for the lions, I wouldn't worry about it and agree with the "just get them painted and on the table" approach. There's something about having a completely painted army that helps those little imperfections seem insignificant. That said, I was trying to figure out what felt odd about the sculpts. I think the manes are too far back, and the posing of the legs is a bit stiff, and one of them has a big underbite, but hey, if they pull a chariot, they do the job!
