I Love the concept you have here! The structure and expression of this animal are very imposing, and the color scheme is one that works quite well with the design. My favorite part is the Oviraptorid lineage, and how you make a family of relatively harmless dinosaurs suddenly become such an imposing monstrosity!
One flaw I can identify however is with the coloring. As I said earlier it does go well with the design, being an Oviraptorid. However, in my opinion the coloration detracts a little from the overall idea that this is a frightening and dangerous predator. Although we have no idea of identifying their true coloration so this could be accurate if such a thing were to exist.
Love this piece, and I sincerely hope that you use it again in the future, hopefully to give an idea of scale.
