This is my very first gif, im pretty new to pixel art so im working with few colors, what do you think guys about this slime??, some advice would be cool!

~Thanks for your time~

Hi Yuran! thanks, jajaj, mm it is more like going to do something :P (like in ready stance), just there happy of life xD.

I think it's strange for a slime to be shedding parts of its body like that, especially with no apparent sign of those bits coming back into the body. Looks more like a lifeless droplet of some fluid.

I advise you to add more frames where the animation of the slime is too sharp :)
For example, add frames where the slam wakes its round shape. (my english bad too)

So, I corrected the jerky frames and timings of your work. Look what I changed, but do not copy my actions. Try to find for yourself mistakes and roughness in the animation, do not be lazy to study other people's work.
