The color scheme is very wonderful. you can never go wrong with complimentary colors! The only thing that bothers me is that there is so much negative space. By cropping it just a little bit, the negative space would not be so large and distracting. As far as the peacock itself goes, it is quite beautiful. the various marks create a fantastic texture.
Very good color choices! Blue and orange are both complimentary colors, so you NAILED it with the color choices! I also like the details on the peacock and the semi-painterly background adds a nice touch. ^^ I do think that next time if you could make the piece look a bit "fuller", that would be good. Other than that, great job!
