Very eery intro, I like the part which you have around 0:30, this would fit very well for an animation of sort as background music for some mysterious and danger-filled scene. Good build-ups and transitions in this, with a nice percussion change at 01:45 and a change in the melody of the bass wobble after this, although I think that it sounds a bit empty here for some time with just the bass wobble and drums, but the synth after that makes up for it. I think that what could improve it is to add more effects to it. At the part before 03:25 when more energy is pumped in again.
Would fit very well for ancient mystery-themed stuff. Good job.
