this is strange, I would concentrate on better ideas for riffs, better melodies and stuff rather then unusual tuning. This lacks something interesting for me.. it seems kinda plain.
On the other hand, if there were good vocals it could change the whole song. Planning on writing lyrics?
All in all 2/5 and 5/10 - mostly for the part between 00:16 and 00:33, that could be a nice heavy part and for the drums. Most of my stuff needs drums or beats and I'm always too lazy to make them.
thanks for the comments. I pretty much just made this as I went along adding drum beats and guitar parts to what I thought would come next. I plan on using the intro for a real song, just have to flesh it out and write some lyrics for it. I will post it once I have it finished! Cheers!
