Whatever the method you are going to use, it's now time to start with the effective sculpting process.
However, first, a disclaimer: in this recipe, I'm not going to teach you how to sculpt, nor is this an anatomy lesson of any kind. For these things, a book itself wouldn't be enough. I'm just going to demonstrate the use of the Blender sculpting tools, showing what brush I used for the different tasks, the sculpting workflow following the reference templates, and some of the more frequently used shortcut keys.
In this recipe, we'll use the Dynamic topology method. If you haven't followed the instructions of the previous recipe, just follow the steps from 12 to 17; otherwise, just open the Gidiosaurus_Dynatopo.blend
file that is provided.
