Johnson Martin is sharing his insights in 3D topology on his blog. It has a section where you can submit your questions too.
I've always had a love for 3d modeling, and I've noticed a lack of organised education regarding making clean topology ever since I became interested in 3d modeling in 2012. So that's what inspired me to create a new resource with clear and simple guides on 3d modeling and topology.
So if you struggle with topology like I do, bookmark or subscribe!
