Nice! I didn't know about the poem either. The art is very charming and suits your text well. As some have said before, I was also wondering about multiple paths... or maybe something that would make the text react more to the player's input. When I saw several pictures on one page (I think there was a wing, the character's eyes. etc.) I tried to click them. You don't need different ending but maybe different ways to examine or "watch" the humming-bird, leading to the same conclusion in the end, could be a way to expand the experience a bit. ;)
