Good first block sculpt model!
Be aware, there are Blender techniques, like armature and rigging. To give your model all the posses you like to give them. Modelling like a stone fixed sculpture makes the model less usable. But it depends on the project you are on.
A warm welcome, and show us your progress.
Welcome to this site.
Very nice dynamic work.
However it depends on what your intended uses is.
It is not optimised for adding an armature, skeleton, that can move the mesh about.
