I think you should swap Scorplack's normal and shiny colorings. I just think its shiny coloring fits it a lot better.
What do you think?
If I thought so, I wouldn't have colored it this way. The shiny palette looks a lot more like a shiny palette, with brighter, more extravagant colors; making the shiny form duller and less stand-out-ish than the normal one would be off.
