Can't provide a screenshot, but my sims are usually very diverse, or has at least one thing that sets them apart from their family and/or other sims. Whether it's different size heads, feet, arms, different body types, freckles (I love freckles!), less obvious looking aliens, uneven lips, angular/round/square face, distinguished older sims ... They also have a style unique to them. I suppose it's more fun for me making sims that are closer to RL, and not simply an aesthetic or sticking to any one 'thing'.
Unless it's grey eyes. I have a thing about this and don't know why, lol. <3
