All the scales on the dragon look really good, I can understand why that took a long time. The color palette of the whole piece goes together quite well for atmosphere too. Awesome design on the armor, nice detail and coloring. However, if I may point something out: The breast plate looks kind of awkward in design. Whereas the rest of the armor is pointy with a horizontal/layered plate scheme, then there are suddenly these two round plates on her chest. It disrupts the flow of the armor and doesn't really make sense. Also curious as to why she is missing a gauntlet.
Thanks for commenting! The round chestplate is there mostly because I wanted to keep the female form somewhat even in a fully armored character, also I don't think it's bad that it breaks the flow of the armor, it isn't that bland this way. The reason she's missing a gauntlet, for one is to break the symmetry a bit, also she was originally supposed to have some magic effect on her hand, but later realized it was unnecessary and just left it uncovered.
