I think this has potential but it is a bit too playful at the moment, a little too "Clip Arty." Could you formalize it in font style and in the presentation of the tree. The tree in the OT represents knowledge and wisdom, fruit-production. From a NT perspective it hits at the cross without overtly forcing that on the viewer (comments by Andre).
well I don't really know about the NT at all as I am Jewish but observant and study Torah every week.
I will work on a different tree... for you - I can add symbols if you tell me which ones. for example eighteen leaves = life in Hebrew - thought of a fig tree as that has significance in several places.
