I dunno, the Brushes in Clip Studio are weeeird and not as smooth as SAI, I didn't have a good feel in any of them, maybe I will download some brushes and see how they work,

As for this, I dunno, drew an Orca that is full of something... but what is it?

Inflation?
Pregnancy?
Victims?
Food?

Why it looks not too pleased?

I'll leave that to your imagination XD
