Very wide mix, I like it :O
The pops and radio sounds and white noise at the beginning seem very original to my ears, very well done there. It was like being located somewhere else than at my room.
At 1:42, there's a high end sample in the middle of the mix. If you listen carefully, you'll hear that its reverb is still going on when the bass comes back in. In general, I find that stopping the reverb as soon as the other theme takes on makes up for a better striking result, and it also leaves more space for other instruments when they are reintroduced.
At 3:25, the high synth doesn't reach exactly the tone I feel like it should reach. I enjoyed this part less because of that. At least, that's what I think.
The part at 3:43 seems to lack a proper transition, I'd say. The mix felt a bit less authentic to me.
By the way, I don't know if you put distortion or overdrive on your drum samples, but in any case I think the base drum is missing some punch. Not sure about this, but... meh, I felt like mentioning this. Maybe try to put an equalizer somewhere in the effects rack, or put some effects that mess a bit with the frequencies of the sample.
I wonder how you made the heavy synth in the drops. You played with the stereo widening, probably voices, and other stuff in a really impressive way. I'm curious about how you did it.
Otherwise: the synths design, structure chosen, mix, selected effects and ideas presented here are very well crafted. Well done, EthoShark!
Can't wait to see more of your stuff :D
