Robot Concept 8N-429

This is an in-progress sketch of a robot character I’m designing.

Its name is 8N-429. What do you think of the design itself so far?:confused:

Body and head show some progress, but the sketch is hard to read. You should get some plain, white paper and a hard and a soft pencil. Start with the hard pencil and low pressure. Apply more pressure to define some areas more. Use the soft pencil for dark areas / shadows
