For happy looking emoticons you usually want to use eyes that are high up. The best characters to use for these are ^, ´, `, or ⌒ among others. The best characters to use for mouths are ones like ▽, ∀ or ω if you want to be cute. You can also add * or # for rosey cheeks or add waving arms with things like \, /, ヽ or ノ. You can also always throw in stars or hearts too.
