I'm working on Aqua's so I need to know

67x70 is the max size for Demirammon. I normally will do 64x64, except for certain cases where I want the entire space filled out (the Blue Archive characters, because of the halo glow)

ok thanks

what if I'm making it on pixilart and bringing it to demi?

?
Just download the image without increasing the scale/resolution
