Nice character art. I admittedly look at the colors and I think of Oreo cookies or non-branded dark cookies with milk cream filling. X3
They look like a pretty feral Dragon. The scale pattern has lots of detail and gives off a lovely impression. The dark eyes make add a mysterious-mystical vibe. I assume you were inspired by the motif of magical Dragons from folklore and fantasy novels. Ryuu has a slender outline that surely gves them a great physique for maneuvers when flying or running.

That would likely be quite the challenge and exhausting to wear a quadruped suit, but wish you much success, should you decide to go back to this project and yet build a suit of your Dragon.
