I quite like how the 'lights' on the first robot ended up looking like bow tie :D And I think I will use the second robot as my Robot Carrier.
From Script to Screen: Characters Development
I think I'm pretty happy with these.At first I wanted my main two characters to look exactly the same, because they are robots and for me they don't have genders. But I tried to change the shapes a bit and imply genders in a way. Might not be successful so I would definitely appreciate some feedback.
Here are my two main characters under the influence of the evil robot - glowing in red and after they get released - glowing in blue. Not sure about the facial expressions, but I definitely want their eyes to look different in the two stages.
