Sounds pretty good, but I think it's too early to know how it will end up sounding...
As an instrumental it will need to develop and stay interesting.
What you have so far doesn't really bring a mood to be honest, yet. I think it'll need more depth and texture...ages spent tweaking each sound...arranging, mixing, and probably won't come together until it's fully produced.
I think it's easier to judge sung songs early on, because they have words and melody and could stand up just busked with guitar and vocal... but with ambient/spacey type instrumentals it's all about the tune, the mood/atmosphere, and the overall sound. The tune you have so far doesn't really grab me, but again it might if the production and arrangement gave it a lot of depth and atmosphere.
Based on the type of music you mention you like... I think the music needs to be a bit trippy, needs to shift the listener's mood pretty much as soon as it comes on in headphones and take us into your world (or certainly within the length of this track it should).
Sounds like a fine start... just too early in development to really give the impression. Unless you feel this is an example of the 'sound' in which case I think it would be wise to revisit it and really work into the sound.
Hope that's some help.
