It’s really interesting to see a strong, knight-like toa for an element like Psionics. Most psionics toa tend to be more manipulative and sneaky from whatI’ve generally seen. The cloak, the flag and the extra detail on the shield are great touches. I also really like the use of trans-dark-blue throughout the build.
Areas I’m not so fond of are the two very separate looking blades of her sword and the grey for that area on her front and her feet, which i don’t think really fits with the colour scheme you have there already. The spikes on her feet aren’t that convincing either since those pieces don’t really end in points - and they’d be highly impractical when walking or running around!
Definitely a really cool toa overall though!
