Just popping in for the sake of being a boring mod, but Tuna, err.
Rule no.2Do not rip artwork. Ever!
Always clearly state what your references were in making a piece. If you sketched in pencil, color-reduced to 1bit and then went to work on it, okay. Ways like this are completely accepted and nobody's going to shout at your for it, but it's good to know anyway. If you stole somebody else's artwork, 1bitted it and then submitted it for critique, not okay. If caught red-handed, by moderators or users, and the case is clear you ripped, you will be banned and forgotten forever. Other similar instances of fraudulent behaviour like posting other people's artwork without permission (regardless of them being edited or not) or jobs without delivering the promised payment will reap similar rewards.
The lower text is not particularily relevant since you didn't attempt to steal artwork, but the first sentence ALWAYS APPLIES.
You did something from reference, you state it. There's no bad intent here whatsoever since you're connecting the piece to the anime consciously with the thread title.
Still, just remember it, dude O:
