cliipso which software are you using , I think it's InkScape, as far as I can guess. Gave some gradients and shadows to make it look more alive.
Make hairs looks more good , you can find hard styles on google, for now it's looking very flat as Somebody said make it little taller.
try to gave black outline , if that looks good , else keep how you like it and want to make it.
Nose is not looking very good, try to see some references pictures and try it mix it.
Hope that helps.
