I wouldn't tilt the bars up any further. If anything, I'd tilt them the other way a hair. Your brifters look like they are in exactly the right spot. You want to be able to drop your forearms until you can lay your wrists on the bar top, holding the outside of the hoods, little finger behind the bar, thumb on top of the hoods. That's your fast hoods position and it should be comfortable for your hands and wrists. If you tilt your bars up further, you lose the support of the bar top for your wrists.
