>>5456472soul is almost always just a problem of gesture + expression, you might be tempted to think it's proportions but it isn't. an attempt to edit it to make it luffy more expressive, but there are limits to how much quick editing can do. the older luffy was drawn with the mindset that he excitedly spots something in the distance, the newer one was done with the mindset of 'oh i'm just redrawing something' which is why the gesture and expression in the newer one is lacking. the eye is the most immediate problem with the newer one - older has him looking at something in the distance while the newer is just staring blankly into space.
