I trully doubt, that you've done this piece by hand and that this is a real pixel art piece.
The background (houses' silhouette) seems exactly like a reduced (and colored) photo.
And why would you let some lighter pixels on the creature's bottom (fingers, legs etc.), if it were a hand pixeled pixel piece and not a cropped, reduced picture?
Why don't you do an original pixel piece by yourself instead of posting this pieces? I also doubt, you pixeled fully by hand any of your last pieces!
Stolen or not it still just looks like your standard sloppy scale-down color redux. Oh, these Jocher-wannabees! 
maybe if i ignore being called out on stealing art, and instead just submit more stuff, i'll go by unnoticed...
I agree with the comments below. You have already submitted a rip and your last 2 attempts at this challenge were suspicious to say the least. Furthermore, several members have already pointed out issues in some of your other submissions.
This post will be your official last warning.
Read the submission rules and make sure in the future you only submit pixel art that is made by you. No RIPs, no edits, no colour reductions.
