Wow! The gold plate is really well done. Some of the richest gold armour I have seen in ages. The overall paint job is also up to your usual high standards. Well done!!
However, regarding the scheme, there are some parts I like and some I'm not so sure of...
The purple and blue do go with the gold fairly well, I think. The only question I have over the overall combo is over the white cloak - how did you shade it, as it seems a 'cold' white - perhaps that's the photo though... Maybe a more 'cream-shaded' white would work better with the warm gold?
I personally favour mail being darker than plate armour as it makes for better contrast in my opinion. Realistically, it does tend to lack the shine of plate. So in this case, I'd start with something like tin-bitz as a base coat and limit the pure gold to a very minimal dry brush where the light hits. However, you probably disagree, which is fine, right & proper...
Personally, I'd definitely paint the hands as bare flesh - the same blue as the tunic looks odd to me. If they have to be gloves though, perhaps a warm, rich, deep brown, as that'd go well with gold...
Am not sure about the pike shaft either, but that's because a darker wood or painted shaft is just my preference. Again, it would provide good contrast. Brilliant though your gold is, there is rather a lot of it on the model. A rich mid-brown wooden shaft on the pike would go well with that fabulous gold...
But, all that being said, if you like them as they are, keep them like that. it's what you like that counts. My opinion is a very insignificant consideration really.
How do they look alongside your other Elves? If they are going to take the field together, that's another consideration...
