I have a rounder face as well. My cheeks are still relatively "full" but my super athletic younger brother has the same cheeks so I think that's just our destiny.
With that being said, I am just over 2 years on T and am SUPER happy about my appearance in general, and multiply that times about a million in comparison to pre T. I was never super feminine in body structure and often was read as male before I was ever even trying but comparing current pictures to old pictures, absolutely 100% happy with how it's turned out. I could work out more and enhance that further, just need to do it. I do have a slight receding hairline but I find that I actually kinda like it. I was worried about going bald but honestly the thought doesn't bother me as much as it used to. Beer gut wise - not for me at all. When I'm actually trying and watching what I eat, no worries at all. As referenced above, I've slacked a bit and could use some leaning but I definitely don't have a beer gut whatsoever.
Overall - very happy with my changes body wise.
