Hey, I think it’s pretty good, but I think it would be better to make it more rectangular when painting! It is recommended that you use rectangular tools or straight-line tools!
i do not have thaat tool because of the site i am use it is called pixelartmaker.com
That you can practice more…… I believe you can do better after more paintings！
By the way, I’m pretty sure that the Artwork category is for art made in Aseprite.
EDIT: yep, it says right here. About the Artwork category - Artwork - Aseprite Community
