This Charr need more work. I bet you like it how it is, but I would go for different armor pieces. To fit with flame scheme, you can dye it that way. I am not sure what should I recommend, as you took screens from only one pose and location. Help me and I help you, if I can :)
I definitely would make use of more color. Using the same set of colors on the same set of armor skins always looks bland. There is nothing inherently wrong with sticking to a single armor set but then the colors really need to bring it to life.
