Nice fibonacci spiral in there, and what appears to be a vagina with an eye peering out from its center. I doodle in a very similar manner as you - always  two-dimensional and cartoon-like with my approach to technique, yet full of painfully intricate details  involving what may be subconscious mathematic techqinues. i also happen to use fine-tipped black felt pans to draw on white paper (preferably with a resistant edge to help with my hand-eye coordination), and start with a simple line or small repetitive pattern that follows the original two-demensional stream-of-thought outline i started through to its "logical" conclusion, if that despription makes any sense at all... the autmocatic drawing method began with the art movement started by Andre Breton in france, who also happened to be a writer who "invented" the automatic mehod of drawing (although I'm sure its always been around). i have anxiety issues when stressed (who doesn't?) and find that practicing this "mindless doodling" not only lifts my depression because i've accomplished something (no matter how small) but sometimes results in pieces I actually sometimes like... random footnote, fibonacci sequences were found in many mandmade tempes and religions from civilizations thousands of year ago, long before mathematicians discovered them. they're very popular in the eastern shrines from thousands of years ago. Anyway, I ramble... To get the the point, I was wondering if you knew of any "art collab" or similar group on Steemit? As in, where people submit a work of their own for someone else to edit, and then the collaborator adds their edit and sends it back to you, and you edit it again, and  vice versa. i've seen some amazing works created on instragram this way... where no one contributor's submission blew me away, but the final edited product contains the best elements of everyone's contribution.
