Thanks for the kind comment..
I hope I won´t forget that part
I know what you´re talking about with the overlapping mesh...
I had a lot of trouble with a bad topo mesh just a few weeks ago
It made me cry
I spent a lot of time to fix that ^^
I would love to give you some advice... and I´ll try..but I just want to let you know that I haven´t much experience
I build my base mesh with the x-symmetry activated...
So the zspheres won´t get twisted...
I think this is important...but I also think you know that already
and I hit the "preview" button a plenty of times ^^
Once I´m happy with the result I hit the "make adaptive skin button"
and edit the existing topology...
to clear minor ( sometimes major^^ ) mistakes in the mesh...
I haven´t a good advice so far I´m just learning by doing ^^
