Mesh issues

Initially i was having problems bringing my obj Maya mesh into zbrush, as the branches would refuse to connect their mesh to the trunk object. This required messing around with the move topology tool and zremshing the object before using Dynamesh.
If I tried using dynamesh before moving the objects around the mesh would still refuse to stick and I was contemplating remaking the tree base with spheres :P, but ended up getting it to weld:

I'm also using the pine tree on the left as a basic reference for now.
