I draw at 2k+ resolution and then compress as needed in the game engine.
If you mean pixel art, there is no specific size, you may need to adjust it to your target style.
I draw and animate in CLIP STUDIO PAINT and blender. ヾ(•ω•`)o
thanks for the reply. I'm also interested in the program in which you draw pixel graphics, and whether you rotate the limbs for animation or draw each frame separately, it's just that I work through aseprite and when rotating the sprite is strongly deformed ( •̀ - • ) (I hope the emojis look appropriate, it's just that when translated, my words seem rude to me, and I'm trying to convey a friendly atmosphere)
