Once the drums come in, it sounds nice!
It's a nice base, but it's just way too slow and not enough happening for me. If I had control of this song, I would put a big solo over every second of it :P I am a fan of the double bass, but the double bass drum at 2:40 is just weird unless you plan on recording chugging guitars over it. You know what, 3:12 onward is basically good (except the choir sound at 5:20!) You should either shorten everything before 3:12, or expand upon it greatly and make it way more interesting. I can definitely see the effort.
