You know, it's very rude of you to make a threat through PM to report me just because I don't think your sprites are very good StarWarsPokemonAdventure.
But if you feel you must know why, then I will tell you.
The animation isn't very fluid for the gifs. Things just kind of appear out of nowhere. Also, the quality is very low probably because you are using a program like the preinstalled gif animator.
On the only one that you made that was created 'from scratch', all it appears you did was minimize the original image, then cover the image pixel by pixel to make it appear as though it were a sprite. I'm not saying you did but that's what it looks like.
No shading. If there is, it's very little. It could at least have a dither on some parts of the shading.
