I like the font you used din #25. I don't think it looks good with a sans-serif font. And I like the placement of #31, but the fonts are the wrong size, spacing, etc. I'd really like to see that design "tightened up." And think it would look better if the text was the same color as #25 instead of blue.
Can you please remove the purple circle from #42 and add a patch of ground like in #62 - and show us examples w/ the icon to the right and above. Thanks!
Can we see, as an icon, some related to an olive branch as the plant. We searched through hundreds of "olive branch" images and really like this concept - which has a strong biblical image. Here's a branch concept we LOVED and would not mind seeing replicated - almost identically or stylized or incorporated into your own icon:
