If you have the british spelling of honour, then do so with favour and favourite. That’s the only discrepency that I can see.

Depending on your spacing on the invitation, I would put ‘three o’clock’ on a separate line below the date, because that line looks much longer than the rest of it. I have seen some invitations that put the year on a separate line, too.
I would delete all the periods at the end of the lines.
