Tried printing the frog from this set at 75% scale, and it came out like this. The original 3mf for this one doesn’t include supports. What should I adjust on my printer to get better overhangs without supports?

I’ve never seen support material visually improve overhangs apart from the specialized support filament that doesn’t bond with the print material. Traditional support always leaves a gap between the support material and the print material, otherwise they’d fuse together and become one with the print, meaning even with support, the print material sags anyway.
OP would probably be better served with adaptive layers and using a much finer layer height in the overhang region.
