the meteor thing going past the screen is very random !
As jay said the text appears too big this is because its breaching the safe action area, allow a bit off the sides in which you place your content.
Also make it more dynamic, the butterfly is very slow and moving in a straight line, make his motion arc and flutter up and down like a butterfly would, their wing beat is faster than that as well i think.
Consider having the butterfly come in or out of perspective.
Also maybe start with a blank screen and have the text appear in a different way, maybe with the meteor (which is too dark), or as the butterfly goes past.
Nice start though, keep at it.
