Yep, I saw it. Good job!

Thanks! They should take a look here then: http://blueheavengame.com/2016/12/19/from-the-kitchen-to-the-table/

You finally cleaned it up! Nice work! Although rotoscoping is not very popular here. You'll always be blamed for the fact that this is NOT a pixel art - although you redrew the image manually. Sad, but true.

Some people do, but the easiest option is to crop the existing one, like I mentioned earlier.

You could also just take a cropped still frame from the animation, and write "animated" or something on it, so that the thumbnail is small, and so that people only see the animation at its best, not at a reduced size.

Ok, thanks.

I'm not sure of understanding that, should I draw another pixel art animation just for the thumbnail in future uploads?

Since the thumbnail is automatically resized from the original, rather than hand-drawn or cropped, it has jaggies and misc colours, which might not be good, and is technically not pixel art since you didn't make it yourself, despite being pixel-sharp. But, I doubt anyone else will notice. I'd recommend making a thumbnail representative of your actual pixel work, but this should be alright. Don't take my word for it though, I'm just a regular PJ user, I have no more say in whether things get accepted than anyone else.

Ok I've been able to upload versions without blurriness. I don't really know what happened the last time since I've done "the same". Is there anything else I've to change?

That's odd, since I was able to use the page I linked to speed it up with no blurriness. Are you sure you didn't also tick some box for rescaling it as well?

Ezgif is exactly what I used for changing the speed of the GIF and, apparently, it blurred the image.

In order to make the thumbnail pass the size limit I had to use the scaled-down version (blurry). I thought a thumbnail was not that important. Now I don't know what to do for scaling down the original without making it blurry.

If your work doesn't get through the curation queue, it doesn't show up in the gallery.

Do you not have a way to edit gifs without resampling them? Photoshop and MS GIF Animator should be able to do it. If you want an online solution, there is EZ GIF.

Thumbnails are subject to the same rules as the full pieces, they also have to be pixel art. Cropping is the easiest way to make a thumbnail. It's also better to use a still frame, so that the thumbnail can be under 10KB - thumbnails larger than that don't display on the front page (they still show up in searches and in your gallery though). The thumbnail being blurry is probably why the first upload wasn't accepted even though you edited the full version of the image.

Pieces with issues usually take a while to get through the queue, even after you make changes. The mods don't come back to them instantly, and they rack up negative votes during the time they spend with issues. It's better to just wait than make another upload though.

It's NOT my intention to get through any queue. The reason why I re-posted the animation was that somebody told me to upload a non-scaled version of it. I did it, I replied with a comment to let him know, and after 2 weeks I got no answer so I assumed either he overlooked both notifications or the system doesn't notify anything. So I thought the best thing I could do was to re-try from scratch.

The blurriness you see is due to I post-processed the animation just to change its framerate (the program I use to build gifs doesn't allow me to choose).

I'm going to post it again with the wrong framerate, without any processing. Hopefully it will be correct enough.

Uploading your artwork again won't help it get through the queue faster.

Neither version is likely to be accepted, because it doesn't appear to be pixel art. Is it automatically rescaled or something? It looks blurry, like it maybe was pixel art but was then scaled down.
