Woah thanks man
I'm not an expert on musical terms in english, exactly what do you mean by articulation? Like I should play some parts staccato instead of legato? Any specific parts you had in mind? Or more contrast between piano/forte (this however I can blame on my sucky USB microphone, recording myself playing Scriabin op 8 no 12 didn't capture the uber-forte of the climax at all)?
I don't like this piece that much on organ, it becomes a little too much of an impenetrable wall of sound in comparison to the piano where the dynamics are varied, you can follow the different voices, etc
Thanks for te replies guys! 
You must not have heard a good organist. When true organists play this fugue it is a real experience.. the voices are all clear, and distinctly articulated. I recommend the recording of Paul Jacobs (not the late pianist, but the living organist).
I mean that there should be more articulation. It's all legato, there should be much more variety. In piano, we can use that to imitate registration changes in the organ. There should be not just a contrast of
forte and
piano, but also different weights applied (this also serves to imitate organ registration).
But in the end, no matter how much specialized technique we apply, it will never sound as it does on the organ. I recommend you learn that instrument!
