Lugia's former Gold sprite, which I felt compelled to revamp. The thing is with revamping, sometimes features need to be changed to match the modern Pokemon as well as shading; for instance, the original sprite had clawed feet and smaller black fins on top, whereas today Lugia has larger fins and paw-like feet. Just look at Raikou's Gold and Silver sprites; its head is shaped incorrectly, and today it has longer legs.
Typhlosion's whole flame collar was also incorrect in GSC formatting, so that had to be redone. Revamps are a bit more than just recoloring, especially if you're a perfectionist like me.
