Can someone make this song sound good?

I heard this guy play the Latvian song on Youtube - called Valodzite -

so I tried to make a midi of it.  Is there anyone here that could make it sound better - by adding

some notes?

I love this. Make it sound better by, and I quote:

That's the best advice ever man. Something's wrong with your music, ADD MORE NOTES until it sounds good! Enough notes, and it'll sound fantastic! The sky's the limit!

Why limit ourselves to some of the notes, some of the time? Why not

ALL THE NOTES, ALL THE TIME?

If that's not a recipe for success, I don't know what is!
