Help how do I turn this blocky seal into a non-blocky seal?

[small fulcrum]

Please help me 🙁

[timid tendon]

While it has its specific uses I wouldn’t recommend going through the process of beveling corners of cubes over and over like a sculpture

the main use case of cubes as a fundamental shape is as guidelines to establish perspective/proportions/lighting

once you’re happy with those you don’t actually need to keep the initial cube shapes

at your stage id recommend drawing spheres inside those initial cubes then connecting the edges like your examples do
