She's supposed to have big heels as seen in your photo, so she's losing a bit of height with her flat feet. She should be about as tall as Andros, and if you were to swap out heeled feet from a Marvel Legend she'd be close to that mark.
The problem is Rita and Zedd. Zedd was scaled larger than he's supposed to be (he's about 6.5", whereas in the show he was under 6 feet), and then Rita was scaled to Zedd. It results in everything being off. Will they scale Ecliptor to Astronema, or will they make him a beast like Zedd? It's a mess.
