Through the intro to 00:52 I thought you built up the atmosphere very nicely - it fitted the title perfectly, and I loved the drums entering - they complemented it really well.
However that high ostinato from around 1:49 onwards felt too loud and piercing. I think that you could have just ended the song there, but it just repeats so many times all the way till the end that by the end I felt the ambient atmosphere you'd built up had disappeared ESPECIALLY 2:30 to the end when you removed all the layers beneath.
I hate to say this but it just felt like an unneccesary extension which made it too repetitive - normally ambient pieces have a larger license than most pieces for repeating but make up for it with sheer atmosphere and texturing, but you remove the texture, just leaving an annoying ostinato.

To summarise, I thought the piece was great but the last minute just ruined it for me.

i love the concept of the song! very ambient yet dazzling.
"radio waves from space" is definitely a suiting title.
well done my friend. :)
