Alright, where do I start with this image.
I'm not usually the kinda guy to get offended at things, especially things as trivial as art on the internet, but as someone who actually has autism, this image actually kind of offended me.
Maybe it's just me, but it feels like the imagery this art uses implies that all (or, at least, most) autistic people are childish, socially-inept, man-babies, especially with first character's use of the chewing-ring.
Also, the irony in the fact that you wrote "Fuck Autism Speaks" feels especially tone-deaf, as you cared enough to bring attention to the awfulness of AS, yet didn't care enough to look at this image and think "Maybe, I shouldn't post this".
Also, I really don't like your art style, but that's more of a nitpick.
Toodles.
