So yeah my first drawing i realised ever in pixels XD and  i would like to know what kind of mistakes i did so i could improve someday.

And i have some questions like: what size of file i would use?
-when i try to change the size of it, it sometimes gets blurry when zooming in or out which makes it annoying. And i would like to know what kind of file i should save so it could have a better quality?

Thanks and i would apreaciate it a lot if you help me =) and PS its also my first time of joinning PixelArt XD

so if your still wondering it's a character created by me and it has still no name, actually its just one random all perfect for practice in pixels XD so it's paochatian^^
