Blender character design practice. It probably impossible to tell but tried new methods of modeling on some of the pieces
Nice work on the art style!
You are trying to do something difficult here: a smooth and rounded character with a metallic material. The reflections will make the slightest flaw easily visible, adding to the challenge. In your case, I can see that some parts are a bit low in resolution. This is going to be especially visible on a metallic surface, because the reflection will have some jagged patterns caused by the angled faces.
If your character is made with a subdivision modifier, you may want to add 1 or 2 more levels on the body and head parts when rendering .
Apart from this, you might want to add some stuff that will be visible in the reflections. Either a modelled scene around the character or an HDRI background. That usually makes metal materials look better.
Thanks for the feedback. The head body and legs are modeled plainly, and the feet and hands are subdivided. Open closer inspection I noticed some of the problems on the body might be because I used a boolen modifier to connect arms and legs instead of connecting it a different way. I will see what I can do for a background.
