To be honest, the first version looked way better. It wasn't poorly shaded,( okay yes it was, but still better) it was just nice and clean.
You managed to mess it up while finishing it. For example the face doesn't fit in at all. It doesn't even need eyes, a visor might work better.
those purple things are the insides I suppose. They really don't look like it. More shadows would make them better.
Can I get the .psd of the first wip? I'd like to work on it
Maybe make it better.
