There's no such thing as a right or wrong color. Colors don't mean anything in and of themselves, they mean things in relationship to each other. Maybe the background you put this raven on is solid black, in which case it'd probably not be a good idea to make it so dark, or maybe you're putting it on a white background, in which case maybe the color is right, or maybe you want to put it in a sunset scene, at which point you might want to tint it red! You need to give a context for us to be able to tell you whether the color is right for that context.
