Litwick: Litwick's shiny is nice; it swaps out purple for blue and changes the eye from yellow to green. The blue still keeps the same "haunted" vibe as the purple and makes sense as a flame color. The only issue with it is that, as you'll see, it's not very consistent with the rest of the line—but it definitely looks fine on its own, which is the most important thing.

Lampent: Unfortunately, Lampent's shiny doesn't match either Litwick's or Chandelure's; instead, it goes for a pink flame (looks a bit washed out in this Home render but that's beside the point) and blue eyes, then tweaks the body by making the glass white and the cast-iron parts brown. It looks good enough in isolation, but it's just not as striking compared to the others in this line.

Chandelure: Chandelure's shiny is really good; it goes for normal orange flames in place of purple, then makes the body an eerie light green and the eyes pink. Personally I might've gone red with the eyes to better match the flames, but either way it's a very noticeable shiny, and pretty cool looking as well. I think it's probably my favorite out of these three.

Mega Chandelure just needed to match regular Chandelure, and it does. Hooray!
