The design looks very good! From the given POV, the tree below (the cone-like leaves one) looks like it has a bigger-than-expected trunk, imo.
I have noticed something though:
The ico one (sphere-like), and probably the other one too, has/have got a bevel on the part of the trunk that “connects” with the ground, which might make them look ugly when imported and positioned on the ground.
The cone-like one has a mixed end of vertices on the above part of the leaves.
