[sarcasm]You suck Endi, you should just quit the 3D graphics field. You never do any good art and you never give any advice.[/sarcasm]
Lol, seriously though, awesome work and thanks for sharing this with us, this is a great contribution to the community.\
I also just watched you timelapse of the retopo of the head (I didn’t know previously that you had posted it) and I noticed the one thing I’ve been doing wrong all along with the retopology, I’ve been just drawing topology onto the mesh with the pen tool and such (which is why I firgured retopo was’nt for me) instead of actually extruding vertices and letting the retopo snap them to the mesh for me. So in short, thankyou very much for posting that video, it helped me out a lot and will make my modeling a lot easier.
