haha we worked together for the past 14 months in the middle earth and have taught each other a fair bit. I taught to model in quads and to avoid booleans. Collin taught me I need to embrace change more, especially zspheres and re topo though as he Kicked my ass in every speed modeling comp. I would get together a rough base mesh in 30 mins while he would have a sculpt out of zbrush done using zspheres that was a million miles better than what I had. My only attempt to try and hold face would be to point out some poles in awkward areas but I had always been thrashed. Plus at the end of the day it is only gonna take 30 mins to retopo the model and have it finished so I can see the benefit and why so many use this method. One time I lost so badly after making a manatee I took it home and finalized the model in maya, rigged and textured it and animated it into a live shot. Wasted about 8 hours but was pretty hilarious.
