I really like it!
This is a nice song, and i too am limited to Finale Notepad. But i use a multitude of programs to put them up here. But to the actual review...
This songs has a nice flow, and the tropicalness is there.
One thing i did notice is that you have i think two or three trumpets, try making them play a little variation each time you repeat the melody. Or maybe even have the trumpets play the same melody put have them play chords.
But overall i like this and is very good even with your computer limitations. trust me. I'm there too.
