So... I wonder how many artists actually even do this. It's super accurate, but really time consuming, haha. I might consider drawing in this more often. Maybe I'll get better at seeing what things should look like and not have to at some point. Who knows.
I tried to match this. Worked out pretty well. [link] Got confused as to how to do the arms though, haha. Need more experience I guess.
The thing is; I did this for the entire first chapter of my book, while my style hasn't changed much since, I stopped doing this anyway simply cause it made my characters look too rigid at certain angles :/ apparently it works a lot better to use perspectively angled references, at least for me. - you see, my style is way too stiff and angled to begin with :/
I think people that use angles like this have a better understanding of how things look in perspective, like comic book artists, but don't quote me on that. I hope to eventually have a better understanding myself. I'd like to not have to use all those lines.
I'd say that's a good thing, since then some would try to keep exactly to the angles and it would kill the overall pic.
