like the shot , as Donna looks so relaxed and natural.As for comments on chin ,the eyes hold my attention so the chin doesnt really bother me.Howevet,have you tried cropping just a whisker more off the chin ,that way i dont think you would loose to much ,or try both one cropping bit off chin and one if you can having all the chin and crop bit from top.also it will prevent anyones eyes from needing to see more .But sure your sister Donna would be thrilled with the out come of shot
