What do you think of my poem?

Just a suggestion, I'm not sure, but it may be more gramatically correct to say "you were born as a snowball" and how do you "keep" that smile upon your face. Overall, I really like it, especially the last stanza which really represents what a snowan is and gives a message to the reader. Your poetery is excellent. Only other thing is "that felt such delight" sounds slightly awkward. The "delight" part is fine as it matches and rhymes with the lines before, but consider changing "that felt such. Anyways, good job, I like it. :)"
