Is though enough reinvention?

I reapplying this cycle after not getting any interview invites this past cycle because I applied too late last summer (September). I have a 3.6 gpa and 504 MCAT. I'm submitting my primaries in June and added a new rec letter from the optometrist that I worked with over the year. I added on 2000 clinical hours from work and 50 hours shadowing. I'm also applying with a committee letter this time and retaking my MCAT in early August. Would this be enough to improve my chances this time applying?
