The melody is very pretty and it's clearly the opposite view from what we've come to expect from this theme. It's bold and it pays off.
Now let's talk technique and improvement :)
Around 1'00" you introduce an electric piano/harpsichord (?). From the start, it seemed to me too mono and too centered (and this is confirmed when at the end it is played with the trumpets). To improve the mix and gain in clarity, you can double your instrument (keep this one and take a very similar one, or have two of the same one at the octave), one well to the left and one well to the right.
What do you think, my friend?
