Young alder. Got most of the details. Some work still to do. I was a bit put off by this tutorial when I first looked at it because a couple of early steps were missing from the description – went from Step 1 to Step 4. However they provided a model of this tree already completed, and with a more detailed knowledge of XFrog it wasn’t too hard to work out what was missing.
My main intention with XFrog is to edit trees from their library to provide more variation in a scene. I don’t really expect to create too many plants from scratch.
