How would split up the tail for this cartoon whale in blender? I am trying to make a potted plant that is in a cartoon-ish whale pot. However, I got to the general whale shape and then couldn't find out how to split up the back part. I used an Iso sphere and then extended out one side for a tail, but I think that because the tail isn't symmetrical it isn't helping. I'm not really sure what to do. I have included pictures of the goal and of what I have now.
I think you should start with a cube or UV shpere which have quads and symmetry topology. Plan the topology before start, then you would know how much geometry to start with. Also, Using Mirror Modifier would be handy for modelling symmetry form.
