You're drawing all this very nicely to a close.

One thing to bear in mind is that using more than 1 or 2 fonts can sometimes make a bit of a mess of a map, so if you do decide to go for a different font for the title, try to make it harmonious with the first - maybe a similar style but slightly more ornate?

I usually use just one font in my own maps unless there is a whole body of text that is many times smaller than the title, and which therefore needs to be legible and readable. For variations I use size differences, bold or italic

Looking forward to seeing how it all comes out
