Ah, been sketching with some general gesture, then fill in form then detail, like a hierarchy. Drawing is.. kinda like doing exercise, if you don't do it - your muscles go to flab again.
But in general, I have nice reference to try work from mostly, when practicing, I'm still not good at building new work yet.
Though, in all fairness, Krea is about as easy as loading the page up, sign in with google or something, share screen, scale the whatever software you're using, put in a prompt, and go! Could use 3D, could use 2D, could use VR, whatever. It is like a fill-in-gaps-er for ideas I suppose.
It may not be hard but it still sounds like a lot of steps XD
Also screen sharing? I'm way too suspicious for that XD
