I tried to sculpt my rabbit with the sculpting tool, but i wasn’t able to do something i liked, so i did it in a different way.
Here with metaball and sculpt tool:
My first character modeling was by using the mirror and subdivision surface modifier (i followed the method on a youtube tutorial, for a human character), i guess i’m used to it now…
Here is my cartoon rabbit :
But this way is probably harder and longer (starting with a cube 
) than the sculpt tool and may be not so instinctive at the begining.
I think i will use the sculpting tool later on my rabbit model for finishes because it seems very useful and powerful !
