Welcome back.
Nice postures, good proportions.
When you learn to sculpt, your transitions from object to object can be made smooth.
Don’t give up, you will learn.
Such a Creative work…well done 
It’s funny you should say that. There is a very fat character I’d like to sculpt and animate and for a long time I thought I could sculpt my way through it, but there are just too many places where the character creates a crevice where I don’t really know what I’ll do about it… and there are lots of other reasons I am interested in blender. Thankss… This scene took me about an hour. 2.8 is interesting.
The you should learn to work with the sculpt tool. But maybe you are too early in the course.
The process is a difficult one and involves many 3D work flows. And can be done totally with Blender!
But have fun and learn step by step.
And I nearly forgot; Instead of using sphere, use METABALL !
Two metaballs next to each other will blend in … magic!
