Overall, your hours appear light (presuming they are what you listed in your application last spring). How much were you working while in school? What part of NY is home?
I agree your shadowing and clinical exposure seem light, which unfortunately didn't impress your state schools where you would have had a better chance due to residency preference. I also want to know how you described your non-clinical experience and how long you have been doing this service (250 hours over... 2 years? 4 years? longer?). Highlight activities you have done since you started college or within the last 2 years. You're not adding a lot of hours to any of your clinical experiences like hospice by the time you apply again... how are you going to improve your profile?
I'm missing the community you wish to serve. I suppose underserved and marginalized is inferred, but it's not clear from the WAMC... it's reasonable for me to presume it's not covered in your application essays and activities. In short, you did a lot, but did people you worked with care? Who are your champions who wrote the strongest letters for you and why?
Also, I don't pay attention to any activities with fewer than 50 hours unless it's shadowing. Saying you'll get 50 hours of food bank volunteering for the next application cycle feels like box-checking.
