I did this (and posted it on e621 too). I didn't set any source because there wasn't one at all, as i've uploaded both here and in the other site yesterday.
I must compliment you on this work, good sir or ma'am. Why dontcha have a place where you can be reached easily for things like commissions, requests, etc.?
Because I draw this kind of stuff when "I can", while I don't have any risk of getting busted on doing so. ;) The less I get known, the better. XD So I can't do commissions or else, sorry...
