Cyborg Art

Today I drew a cyborg and thought I would share it on Super Snail Games. Well here it is:

What do you think? If you're wondering 'What the heck is that blue thing on his side?', well it's a drench coat. I was thinking of putting it on both sides but decided not to(dumb move).
I believe I didn't put enough detail on his body part and made his robot arm way too big.
Comment your thoughts.
