Hi, This is my second Pixel Art atempt, can you help me with a advice ? 

Thanks @irneaart,  I try to correct the problem of colors in the export .GIF now has 32 colors. (in the next practice, i will try to use less colors). you're right with the caterpillars, i will try to give more time to animation phase. Thanks a lot for the tips  !  

@Goodlyay i think the problem of the stroke is because i am more illustrator than a pixel artist, and i use the tablet a lot, i will try to correct this problem, being more prudent with the tablet and trying to use more the mouse. Thanks for the examples, i will improve my corners whith your trick. Thanks for the tips Goodlyay :D ! 

I share some more of my work as an illustrator.
