Your levers are really, really low, and the bars are rotated the wrong way.
You could rotate your bars slightly down (so they point towards the rear brake bridge or rear hub, depending on who you ask) and move you levers up so you can sit on the hoods to brake. Even a centimetre.
Like this (not the best example though):
Older bars and brake levers were designed so you'd brake in the drop and so forth.
Modern brakes and bars are designed to brake from the hoods and drops...
If you got a more modern compact bar, I'd suggest replacing the brake levers to something more modern as well (SRAM, Tektro, etc), otherwise you're just wasting your time.
A slightly shorter stem may help, but you'll still be braking from the drops, not the hoods.
