Not bad.
You really set this one up good to add vocals in it. Also, you set it up good for it to need a solo too. =P This will need a lot of vocals though if it's to cover the entire thing. I couldn't imagine making vocals for something this long. The ending wasn't bad though. Maybe ending it with something a little more heavier and everything. The instruments did sound of bad quality, but I see that these were done with old equipment.
