I don't really know what my face looks like thinner as the last time I was that thin (pre first baby) was 14 years ago. My butt I can cheerfully lose.
Another suffer of skeletor face syndrome here
I'm just resigned to the fact that I look and feel a bit better at the bf% level that stops my abs from being as ripped as I might like.
My face looks gaunt and a few years older, than when my lower abs aren't as defined.
Maybe if I put more effort into increasing the mass of my ab muscles they may look how I'd like them to at a higher bf%...
But that tends to start a vicious circle as they quickly overpower my chesticles, so I have to eat more and lift heavier to build them bigger, which makes my shoulders and arms look smaller... Then my chicken legs look even more spindly and pretty soon I've packed on 10kg of muscle, outgrown my clothes and no longer have the lean hard look I'm after (I'm not short, so look square when I'm heavier, especially when fully dressed
