Academic. The issue is not whether that is a possible position, the issue is that cow should be careful to not default to stuff he draws without being critical about how he's come to adopt them.

I asked, if he stood like that normally and he felt comfortable with it he could keep it, but if not, then I urged him to check why he drew that angle, that's all.
