Wut?
Firstly I'm sorry I can't check your art cause I can't connect to disocrd, censorship shit. Sad.
Secondly I'm totally a noob. This is the first time I ever try to make pixel animation, or pixel drawing, or anything art related. I don't have any advise to share, cause I'm barely trying to figure things out myself. By touch up I don't think you mean you want me to ruin your work...
Sorry but I can't help you. I'm more in need of help rather than can help others.
