Badbot

My first attempt at pixel art is this robot who looks like a badass, so I called him Badbot. I haven't studied much about game character design yet but have started getting interested in it lately. I realize it requires a lot of skill and patience and I'll definitely spend more time on learning how to do this better.

Attached is a shot with him to scale so you see how he would look actual size in a game.

Feedback and tips or tutorials on how to get better at this would be appreciated!
