Both are very nice. The use of the cross as the leaves is subtle but powerful. Nicely conceptualized.
For #12, could you please drop "the power of effective giving" and spread the word "FOUNDATION" out under the ground. It might not look good spread out, but I'm willing to see. Maybe even another sample where it was centered in the middle would be good.
For #11, if you could justify all of the words to be in-line with the "M" on Mission, i think it would be perfect.
Thank you very much for your work.
