I want to start off by saying i love what youre trying to do with this look and your look for ara the lesser dragon. I think this look would benefit from some color changes though, I think this red, gold and yellow are a bit too cartoony. Maybe try dying the metal parts with something a little more realistic for metal to be dyed, like gold as opposed to yellows and reds. I would also try to add some more neutral tones like browns or off-whites. I think the armor skin choices themselves are fantastic though.
