Kia Ora Alex,
Nice piece. A few suggestions:
Although tabs are quite common for notating guitar parts in pop styles, classical guitar pieces are generally only notated using standard musical notation. While you can still include a staff of tab in your score, it might be more conventional to remove it.
If you do choose to include tab, please, PLEASE get an actual guitarist to write it out for you. The tabs generated by notation software are almost always shite and the one that Musescore generated for you is no exception. It has suggested some ridiculous unplayable shite (like in bar two, who the hell has hands large enough to press both the second and seventeenth frets at the same time?!) which render it's inclusion in your score quite pointless.
All in all, this is a good start. I'm excited to see where this piece goes next!
Ngā mihi,
Archie
