I never give makeovers to townies or pre-mades. Some look decent and some are terrifying (townies), but as in real life, not everybody needs to have model look and perfect features so I leave them in peace. But when my sim is getting close to one, then I will help them a little in CAS. I tried not to change features too much just correct some weirdness like ridiculously large lips or lack of chin and they get wardrobe overhaul. But the main goal is to let them still resemble “themselves”.
