I kept the habit of my 'direct ballpen' training and I'm trying now anatomy on various perspective.
It's mind breaking difficult and I still fail in most of the case. But I still feel I'm learning a lot, so I'll keep pushing.
If you wonder why so many Cammy of Street Fighter: it's the first character that came to my mind when I wanted to study body anatomy in transport without going NSFW (but I'll CW here for that).
