It’s pretty easy to alter proportions in Clip Studio to at least get a customized mannequin going. Making a bulkier type makes the anatomy wonkier but still works for layouts. This was some customizing/importing experimenting I did getting to grips with stuff. The female characters are slightly different heights & builds and there’s more extreme troll & goblin stand ins.

I know I’ve posted these before, but here’s glimpses of some of my Clip Studio layouts. I’ll admit, I’ve been bouncing over to Procreate more for some of the drawing work... but both programs are excellent and have strengths of their own. I’m constantly torn on my workflow & deciding what to use...
