Very touching. Nice translation. Just a few thoughts to share.

你可以轻轻地来,
手拈一枝笑梅,

Here, you came, quiet, as the poem said,
without a little rose, ....

Would it be better to translate as

holding a little rose instead of without a little rose?


春天，我喜欢发生些意想不到的事情

Oh, I like the surprise, and your big nose (nose or rose?), liking be always in your sight.

How about adding spring after Oh?

Oh Spring, I like the surprise, and your big rose, liking be always in your sight.
