Sorry, I hadn't realized that I shouldn't do that kind of stuff
It's fine.
But realize it is not just because we want you to follow the rules of Pixelation
You should do the work by hand for your own interests.
I strongly encourage you to take your original image and draw over it.
Try to take it in at least 3 or 4 directions, compare them all and then clean up the one you like most.
So I edited it slightly, changing the tint of the tongue to what you would normally expect a tongue to be, do you think this was a good call or bad?
Well it's really just a matter of choice.
I went for color re use so I picked out some colors that were noticeable but didn't stand out too much.
If you want to add a color specifically for the tongue I'd recommend using it in a few other places in the image.
