"her pleasing smile gives me a pleasant experience." my idea is that, 'pleasing' - the adjective ending in "ing" (participle adjective) deals more of our emotion / feelings - causes us to interact. what does her smile brought you? 'pleasant' on the other hand, merely describe the attribute of the noun. how do you describe the experience of seeing her smile? :)
