Big chest and large rib cage. Bad?

Right. So I have quite a barrel chest, big ribs etc, but this means that my stomach, which is sort of toned in a 6 pack sort of way, dips in slightly (ie, it's not really flat from the top of my ribs). It feels slightly..uneven. I also think it looks ridiculous. I know there isn't really anything that can be done about this, but is there anything that could make it less obvious? And is it really that weird or am I just making a big deal out of nothing? And also (obviously) do girls mind big chest and ribs? Again, just a ridiculously paranoid teenage boy. Thanks!
