Nothing like getting a head start, I suppose.

The ornament silhouette doesn't really work for me. Maybe the pattern in the clef could be made more snowflakey?

Why is the type so many different sizes? Restraint is always tasteful.

Why is "Joyous" capitalized?

Not so wild about the swashy initial 'W'. Perhaps it would be best to replace all of the text with a more scriptlike serif face like Brioso or one of the ten gazillion excellent script faces that have come out over the last few years.

I read the ornament as a cartoon bomb, the top right ornament seems superfluous as does the full stop at the end of the message.
You need to spend some time working on the type; it seems tracked too tight and the relationships between the lines aren't working in terms of size or alignment and further have little relationship to your note device.
