Thanks for the comment!
Yes, indeed the original idea was to both Jake's arms and legs get merged. But ... I'm not succeeded in this
Great that you got a fun!
I think the full piece would make a better thumbnail than your actual thumbnail xP
I tried following both arms to see how far I could get, hoping they'd turn out to be the same arm or something. Alas, it's not very far into it that they become ambiguous. Even if there are no secrets to discover, it was fun.
