I mean... For me I've been drawing as a hobby since I could pick up a pencil so it's kind of a thing that I know I'll never stop doing even when I take super long 3 month breaks from even touching anything art related. Personally, I don't usually draw to get appreciation from other people, which is why I share maybe 1 out of every 50 pieces to either my friends or on the internet. I do it out of admiration for whatever I'm drawing, which in this case is Naruto, and add my own flare to it to add on to what already exists to satisfy my need to see a concept that will never happen in canon or just plain out appreciate the aesthetics of a character design, if that makes any sense. I'll admit that I really want my stuff to be praised when I post, so every little comment is enough to keep my spirits high which leads to more posting, but ultimately I'm just drawing to make myself happy, and if other people like it then great! If not, it still doesn't bother me.
