You see, I am someone that is visual. I mean that I'm really good visually. If you talked to me about an old game I played, I could not remember it but the SECOND I'll see a picture of it, it'll all come back to me. This also go for explaining. If you try to explain to me something (for example a commission), having a visual picture to explain help me. Doesn't necessarely needs to be the pose you want, or could be just part of the pose / scene itself. Point is, it just need to be there to say "like this", to give a visual example of what you mean (+ precise some tiny detail that is different from the picture if needs be.). In any cases, hexuza just got a pretty neat concept for that. I don't know exactly how it work, but by what I see it's really neat and could help a lot for people like me.
