“Buddhish” Cover

I’d like some feedback on some potential covers for ‘Buddhish’:  the Unfeeling Doctor’s Freefall into Buddhism, Grief and Grace. (Yes, Buddhish, as in a little bit Buddhist.)  I want to convey grief and hope as well as Buddhism. They must work as thumbnails (teeny ebook pics) as well as larger sizes. Matt suggested I drop the subtitle for the thumbnails. Thoughts?  Many thanks!
