Pretty simple, keep working!
You should try to shift the feel of the song. I get the feeling in this song that all thats really going on is a change between using a wind instrument for the lead and using a guitar emulator. The chord structure doesn't really change, so it's kind of like the same thing played over and over again on different instruments. I don't mean to make it sound like I hate it, because it sounds great, but I think it's somewhat dragged, and could use more work.
Mate, I completely agree with Gorgorothx...he said everything that needs to be said and was very critically correct about the whole thing. In spite of the overemphasis on the guitar this is an excellent piece. Keep making more mate :)
I like the beat, and the overall feel of this. The guitar tone fit surprisingly well, although the actual timbre of it kinda made my ears bleed. If you can, try to emulate that with a real electric guitar (or a better plug-in), and it would sound great. Good use of varying sounds/instruments though... 4/5 8/10
I searched the internet for hours upon hours, just to find a good distorted guitar sample. That one was the best I found, and it still sounds bad unless I use some filters on it(which in turn produces a bit of ear bleedingness.) I would absolutely love to record a real electric guitar for this song, and probably will this summer. Going to Norway to work for my grandfather and he has a small studio in his garage.
Actually, I opened up fruity loops after reading your review and tried changing the sound of the guitar a bit. The more I tried to remove the ear bleeding, the more it sounded like a high pitched buzz, and lost the powerful and harsh sound it had before. One solution on my side might be turning the volume down a bit, since it's a bit louder than the rest of my songs..
Anyway, thanks for a nice review!
