I'd say you should loosen up a good amount, especially with your preflop raises (never limp first in a pot, raise Axs, mediocre broadways, and SCs in position, reraise loose raisers with position or out of the blinds on a likely blind steal with solid but not spectacular hands like AQ). I've found that a vpip in the 25-30 range and a pfr of 15-20 is close to optimum.

You are evidently playing quite well after the flop, so I think loosening up would serve to get you a lot more action and make you more money in the long run, if also increasing your variance.
