it's quite good for a first chao but i agree and think the head is too big. try to keep trying at jirachi but if it's head always turns out that same size maybe try on a simple pokemon like ditto or diglett.
i hope you keep trying at new chao and i'll keep watching you and your chao to see how you progress at making them.if you get good enough maybe you should open a shop for requests.
Chao have all black outlines, I would either stick to that or use the pokemon sprite style outlines. Its very difficult to proprely see the custom parts becuase of the lack of outlines. Also, try to not make one side exactly the same as the other. Yes, its easier that way, but it makes it look... unimportant. If the creator took such ceap short-cuts, why should we spend time admiring their work?
