In my opinion I feel like you could use some reference for the materials. The colors don't seem varied enough. I can't tell what you were going for. Is this suppose to be gold?
I recommend added roughness or scratches to the armor pieces. She's a warrior so she would take damage or have some dirt on her. It can add to the believe-ability more
In LOL, since you see the character from an isometric view, you can just darken the legs up a bit more. I think you did a really nice job on the sculpt. Since this is handpainted anyway, it didn't have to be to super clean. Looking at you reference, you could'v used more colors in the final. You have purple and blue crystals that look really nice. The girl with the helmet shows that a goldish material can work really nicely with blue gems. The areas on the model that are white could be blue. I hope this helps and that I wasn't to harsh or anything.
