Wanted to spend some time in speedtree. Decided on a mangrove as I could make some fun forms with the trunk while also wanting to test out frond and freestyle adjustments.
Unreal Render
Topology
Used some of the default assets for the leaves and branches, but edited the mesh and added anchors to build from.
A before and after look of the tree from my freehand adjustments to the limbs and roots to give it the form I wanted.

Threw together a real fast Unreal scene for a thumbnail render and a bit better presentation. Scatter terrain all came from the "Rural Australia" pack in the marketplace. Mountains came from "Landscape Backgrounds".
