The left hand one looks nice and hand drawn, very 'arts and craftsy' but I would be concerned that it would lose it's details when used at smaller sizes or seen from a distance. So for practicality I prefer the right hand one however I think it is lacking the hand drawn look, maybe try something a bit inbetween like a finger painted style or something. If done right a literally 'hand made' look would fit the 'spiritual' feel well too.
I like the design is good, have you tried the eye with the pupil in different locations? What was the reason for having it looking up?
Also it reminds me a lot of this

I like it.
