I'll be popping in from time to time listening in and giving helpful tips to you and everyone.
You know, I have this song on my iPod, and I think it is very relaxing and nice. I can see a little rural island that's semi tropical, a quite fishing village near a more foresty expanse, people buying and selling in the streets, small boats coming in and out of the docks.
Seems a lot more serene than the island I came from. Mine is a lot more city like and urban (at least half is). Lots of people, cars, buildings, traffic, McDonald's, and so forth.
On my island, every house in the rural side was on stilts, because there would be serious flooding with hurricanes every few years. The second story was always the main living area. I grew up thinking this was normal! How about your home?
Now, somebody had an issue with the guitars not strumming enough or something like that. First, I personally like your song the way it is. However, if you would like a couple of cool guitar VSTi's that allow you to strum at different speeds with MIDI, I think I have just the tools for you.
Here are the websites:
Now, on at least one of those, you can change the speed of the strumming as well. Press a chord of 3 on your computer keyboard, and the VSTi will automatically strum a 6 note chord one note at a time. Lift one finger up from one of the keys, and press back down again and again... then you'll get a strumming back and forth effect like in real life.
Really nice sound out of both of these tools. Then you can record clips of those strummings, and plop those samples into any of your future SNES tunes.
As I said, I like it the way it is, but the tools I posted about here will give you very realistic guitar sound with or without strumming.
