Hope to see the final production. I really can't make too many suggestions on this, but hopefully, that's like, and intro, and outro, or something, because a general rock loop like that just screams for some rocking action. I would say right now, this is more classic rock feeling, so if you wanna keep it in general rock, it would be kinda cool to hear some pumped up parts. And most importantely, have fun with it!
-P.S. Check my audio page, there's more on it than your last visit : )
