I used to carve trees with a Dremmel into cell cast acrylic. A Dremmel is a bit overkill to use to carve plaster. It can be done, but the high speeds will tend to liquify the plaster and sling little white droplets all over the place if there is any moisture in the plaster. And if the plaster is thoroughly dry, it will create a fine plaster mist dust storm, so I always continue to use hand tools-- everything from woodworking tools and dental tools to sharpened nail files. This is my incised tree, shown below an example of an acrylic carving; its' inspiration.
Some might have already noticed a second tree can be made from this model if a new model is cast from it, where the recesses become relief details, shown next. In this way, one version is the negative of the other.
