This could use a lot more work before being accepted. There's no instrument definitions, which makes everything default to @0, and the result doesn't sound very great. Varying up your instrument choices can make a world of difference.
Next, there's no mixing at all. Changing the volumes, and potentially panning, on different channels could make the different channels blend together more elegantly. However, before even getting to this step, you need to figure out which instruments you want to use first.
Finally, there is no optimization at all, and for very obvious things. In fact, almost every line in this port can be put in a loop and drastically reduce the insert size.
All these things considered, it seems like you just took a PetiteMM output and only added the channel definitions. That's not enough to make the port sound good in SMW. I'd strongly suggest checking out Wakana's tutorial so you can start from the basics and build up your porting knowledge.
