I like!
I'm not in favour of cutting the ending celebration from TPM. I assume you cut it (as you cut the scenes between the battle and the scene with Yoda) because you weren't changing anything, rather than because you'd want to remove it from a complete edit, but I'd still like to put in my reasoning for keeping it.
It doesn't contribute anything to the story, unless you take the idea that the Big Shiny Thing is the Kyber Crystal or the Lost Orb of Phanasticoria or whatever that the Naboo stole from the Gungans. But it's important if TPM is to work as a standalone movie (which as the first in the series it should, sequel hooks aside). If it's cut out, the movie is too obviously a first chapter; and it's too dark an ending for what is otherwise the lightest movie in the series. I also like what John Williams did with the scene: using the upbeat and triumphant rendition of what becomes, six films later, the darkest theme in the series.
