Invitation Pocket folds Part 2

After my design meltdown last week, I think, think! I may have settled on the final design for our invitations...

This is our test pocket fold so it's looking a bit tatty now.  I need to find a way of attaching the pearl heart (I've used a sticky dot to secure it for now)

The ribbon is a lot more purple in real life, you can't really see but there is also a purple trim on the edge of the envelope flap.

So what do you think?  I'd love to hear your opinions and suggestions!
