Amazing work, Doris, very glad to see this here on top row! I am also really loving the dyntopo sculpting and trying my hand now at more than single objects - and it is very much like playing in real clay 
thank you again 
baho pwet, yes it would not hurt to add microdisplacement to the bark to the tree too. i agree.
yhago. thank you for kind words. i add an image showing the main steps in creating this piece.
yes craig! exactely, dynatopo is almost like real clay. this is why i love it, i love it even more than zbrush dynamesh, as this latter feels stiff, since the polygons do not change automatically, but only on demand. clay is life, dynatopo sculpts too enjoy sculpting, and when you have question you know where you find me

Very beautiful
Thank you for the break down, this is very close to what I am trying to do now with my sculpts. I started using an empty for each set of sculpt objects so that I can move/rotate/scale the empty as a parent to the bunch of sculpt meshes, and I have been using the cube empty since it makes it easy to select and move, and then reselect the sculpt and already be back in sculpt mode.
I do like the way 2.78 has the ability to stay in dyntopo with a check box now, that makes it much easier to work with multiple objects.
Stunning work once again. 
Very inspireing. Good job.
