It seems as if 80% of blender's learning resources are aimed at realism. People are completely obsessed with realistic models, animations, etc. It's slim pickings for those of us looking to create more stylised material, despite how better suited it is to indie games.
One large problem is finding references to practise our skills on. Blender pros heavily recommend beginners use reference drawings to practise making models. But almost all of these are realistic. They're often tracings of photographs. So, it's difficult to find abstract reference materials.
You could argue just make a low poly whatever character, with no references. But then what of the other assets? How could I match the design for surrounding buildings, furniture, props, items, etc?
