Heh. I poke around and find that people have already took a shot at their own palette swaps.
 
I can’t say that I completely agree that your color palette is as unified as my own shot at this: >>247066 The dress colors still feel very different from Luna and probably isn’t complementing her colors that well.
 
I think your grays are too neutral. While they aren’t clashingly warm or saturated as the original, my own coloring attempt changed the red-violet to something much cooler in color temperature. I also turned the color scheme to be something more of an analogous sort (blues, indigo’s, violets).
 
There is also the issue of the gold attracting more attention to themselves (even worse as Luna’s colors are all dark), My color edit changed them to be silver, something much more neutral and doesn’t attract too much attention to themselves.
 
But, there’s probably more to this black and gold color palette that I’m overlooking, but who knows. I guess I just approached this differently.

Looks very nice…  
too bad they had to make her a stereotypical girly princess dress

Well the horseshoes should match.

I like it.

I think you’d be better off doing that - just realised I messed up Luna’s mane somehow! :T

I kept thinking that yellow looked weird on Luna.

I think you should replace the gold with red.  

I could make a recolor with those colors if you want

better indeed

God, she looks brilliant.

Much better!

nice pimpin luna

Actually, she does look good. But with Sid being the artist I’m sure there something dirty in here.

no

That’s better.

Black and gold. Nice.
