Nicely done. I think it looks good. Especially since you burst it with flash which usually adds too harsh a light in situations like this. The light here looks more diffused allowing the colors and highlights to stand out. More DOF would be nice but you have a decent amount here. My only suggestion might be, since you have absolute control of the subject, to shoot from a different angle to eliminate the blurry tail(?) in the background or to pose him/her on a more natural setting.
